  16. 16. 18 IPv6 Deployment Options  IPv6 Only IPv6 is the only protocol operating in the network  Dual Stack (in devices/hosts and networks) IPv4 and IPv6 operate in tandem over shared or dedicated links  Tunnelling over IPv4 or MPLS IPv6 confined to the edge of the IPv4 / MPLS core IPv6IPv6 IPv6 IPv6 IPv6IPv6 IPv4 IPv4 IPv4/MPLS IPv6 IPv4 IPv6 IPv4 Dedicated Links Shared Links Tunnel IPv4/MPLS  Protocol Translation (Moving to Standards in IETF…) Allow IPv6-only devices to communicate with IPv4-only devices Applications Dual Stack Aware
  17. 17. 19 IPv6 Requires Unlearning & Learning  Basic Changes Extension headers, Fragmentation  Addressing syntax 2001:0db8:0000:130F:0000:0000:087C:140B v/s 192.168.1.4  Routing Protocols OSPF v3 v/s OSPF v2, ISIS, EIGRP, BGP, RIPng  LAN Protocols ARP v/s Neighbor Discovery, ICMPv4 v/s ICMPv6  Different Security Issues and Solutions ACL v/s RA Guard  IP Addressing assignment methods DHCP v/s SLAAC, DHCPv6-PD
