Webinar topic: BGP tuning: Peer with loopback
Presenter: Achmad Mardiansyah
In this webinar, we discussed BGP tuning: peer with loopback. a loopback interface is a virtual interface, which is always ON and will not be affected by physical status. therefore it is very useful to use it as a peering parameter to ensure high availability of BGP peer.

in this GLC webinar, we are discussing about how to detect networking virus using mikrotik. the topics starts from what the virus is, how it works, and then what routerOS can do to deal with them.
In this webinar, we discuss a feature from mikrotik routerOS that is called fasttrack. This feature will improve routerboard performancce for particular connection. unlike fastpath, using fasttrack requires trigger from firewall filter/mangle.
Correct understanding of connection and connection-tracking is very crucial when configuring the trigger.

Presenter: Achmad Mardiansyah
In this webinar, we explore how to use firewall mangle rules and policy-based routing to steer outbound traffic along a similar path to inbound traffic. This technique can help to balance outbound traffic across multiple links, ensure that outbound traffic exits the network through a particular gateway, and more. We provide a detailed overview of the configuration process and offer examples to illustrate the benefits of this approach. Whether you are a network administrator or just want to optimize your internet connectivity, this presentation has something for you!

Wireless communication involves the transmission of information over a distance without the help of wires, cables or any other forms of electrical conductors.
Wireless communication is a broad term that incorporates all procedures and forms of connecting and communicating between two or more devices using a wireless signal through wireless communication technologies and devices.
Features of Wireless Communication
The evolution of wireless technology has brought many advancements with its effective features.
The transmitted distance can be anywhere between a few meters (for example, a television's remote control) and thousands of kilometers (for example, radio communication).
Wireless communication can be used for cellular telephony, wireless access to the internet, wireless home networking, and so on.

7 OSI layer & protocol
● OSI layer Is a conceptual model from ISO (International
Standard Organization) for project OSI (Open System
Interconnection)
● When you send a message with a courier, you need to
add more info to get your message arrived at the
destination (This process is called encapsulation)
● What is protocol
○ Is a set of rules for communication
○ Available on each layer
● Communication consist of series encapsulation
○ SDU: service data unit (before PDU)
○ PDU: protocol data unit (after header is added)

Router and Routing

● Router is a network device that is used to forward packets, based on layer 3
information (layer 3 header)
● Routing is the process of selecting a path for traffic in a network, or between
or across multiple networks

Routing table:
● A table at router that is used to forward packet
● Available on every devices (router and host)
● Entry is executed sequentially

Routing metric
● is value used by a router to make
routing decisions. It depends on
routing protocols
● OSPF: accumulated cost
● RIP: hop count
● IS-IS: cost
● EIGRP: bandwidth, load, delay,
reliability and MTU
● BGP: AS-Path, Next-hop, Origin,
Local preference, Atomic aggregate,
Multi Exit Discriminator (MED)
23
24. www.glcnetworks.com
Asymmetric routing
24
● Currently, routing is done one-way only
● Forwarding process on router is based on destination IP address
● There is no guarantee incoming path is similar to outgoing path
● We can only control outgoing forwarding

● Dynamic routing protocol, Path-vector
● Connecting AS numbers
● Each router need to create BGP-peer
○ Only receive and send routing prefix to peer
● At Layer 5 (session): use for BGP peer session
● At Layer 4 (transport): TCP port 179
● Used by all routers in the internet
● Routes contents:
○ Full routes: all prefix in the internet
○ Partial routes: specific prefix
Need to consider:
● Requires knowledge to operate
● More complex (compared to RIP), lots of options
What is BGP?
26
27. www.glcnetworks.com
● A collection of Routers & Networks
● Under one administration (organisation, company, etc)
● Defined by AS number, given by IANA via RIR (APNIC, LACNIC, AFRINIC, ARIN, RIPE-NCC)
● We run BGP between AS
● Inside AS we run IGP (Interior gateway protocol): RIP, OSPF, IS-IS, EIGRP, etc
Autonomous number (AS), IGP, BGP
AS1
AS4
AS3
AS2
R1
27
28. www.glcnetworks.com
HOW BGP works?
BGP steps
● Each router must have router-id and AS number
● Each router must create BGP peer
● Setup BGP filter:
○ Inbound filter
○ Outbound filter
● Exchange routing tables between routers
● Send keep alive periodically
28
29. www.glcnetworks.com
BGP attributes
BGP metrics are called path attributes. Classifications:
● Well-known (all router must support)
○ Mandatory (must exist, in every update)
■ AS-Path
■ Next-hop
■ Origin
○ Discretionary (not always exist)
■ Local preference
■ Atomic aggregate
● Optional (some routers do not support)
○ Transitive (If not recognized, marked as partial and still propagated to neighbor)
■ Community
■ Aggregator
○ Non-Transitive (If not recognized, discard)
■ Multi Exit Discriminator (MED)
29
30. www.glcnetworks.com
BGP best path selection algorithm
1. Router is ignoring received path if the route is not valid. Route is valid if:
a. NEXT_HOP of the route is valid and reachable
b. AS_PATH received from external peers does not contain the local AS
c. route is not rejected by routing filters
2. The first path received is automatically considered 'best path'. Any further received paths are compared to first received to determine if the
new path is better.
3. Prefer the path with the highest WEIGHT.
a. WEIGHT parameter is local to the router on which it is configured. A route without assigned WEIGHT have a default value of 0.
4. Prefer the path with the highest LOCAL_PREF. It is used only within an AS.
a. A path without LOCAL_PREF attribute have a value of 100 by default.
5. Prefer the path with the shortest AS_PATH. (skipped if ignore-as-path-len set to yes)
a. Each AS_SET counts as 1, regardless of the set size. The AS_CONFED_SEQUENCE and AS_CONFED_SET are not included in the AS_PATH length.
6. Prefer the path that was locally originated via aggregate or BGP network
7. Prefer the path with the lowest ORIGIN type.
a. Interior Gateway Protocol (IGP) is lower than Exterior Gateway Protocol (EGP), and EGP is lower than INCOMPLETE, in other words IGP < EGP < INCOMPLETE
8. Prefer the path with the lowest multi-exit discriminator (MED).
a. The router compare MED attribute only for paths that have the same neighboring (leftmost) AS. Paths without explicit MED value are treated as with MED of 0
9. Prefer eBGP over iBGP paths
10. Prefer the route that comes from the BGP router with the lowest router ID. If a route carries the ORIGINATOR_ID attribute, then the
ORIGINATOR_ID is used instead of router ID.
11. Prefer the route with the shortest route reflection cluster list. Routes without a cluster list are considered to have a cluster list of length 0.
12. Prefer the path that comes from the lowest neighbor address

BGP best practice: use loopback for BGP peering
35
Benefits
● Loopback interface is virtual → always ON
● Loopback interface is agnostic to physical status
● Resistant to topology change (with help of IGP)
● Very helpful for internal BGP (iBGP) peering
● eBGP can use loopback address too
36. www.glcnetworks.com
Peering with loopback
● Make sure loopback addresses are
reachable. For example, via IGP: RIP,
OSPF, static route, etc
● Remote address: use peer’s loopback
address
● Source address: Use our loopback address
