Cisco routers do not route IPv6 by default, so this capability should be activated with the “ipv6 unicast-routing” command. Cisco routers are dual-stack by default, capable of running IPv4 and IPv6 simultaneously on the same interfaces.
IPv6 allows the use of static routing and supports specific dynamic routing protocols (i.e., variations of the IPv4 routing protocols modified or redesigned to support IPv6), as follows:
- RIPng (RIP new generation)
- OSPFv3
- EIGRPv6
- IS-IS
- BGP
Note: IS-IS and BGP experienced the least number of modifications in . . .
