IPv6 Multicast Routing with BSR

R1(config)#ipv6 routing
R1(config)#ipv6 pim bsr candidate rp <IPv6 Address>
R1(config)#ipv6 pim bsr candidate bsr <IPv6 Address> priority X


BSR and RP can't be on a single router.

VRF Definition in IPv6 (Multiprotocol VRF)

vrf definition [vrf-name]

creates a multiprotocol VRF for both IPv4 and IPv6

IPv6 Redistribute with include-connected

For IPv6 whether or not connected links are included in redistribution is up to you at the time of configuration.

Differences between OSPFv3 and OSPFv2

1. Configured using interface command
2. Advertising multiple networks on an interface
3. OSPFv3 RID must be set
4. Flooding scope (link-local, area, AS)
5. Multiple instance per link
6. Source packets from link-local address (except virtual link)
7. Authentication using AH / ESP
8. New LSA Types:

1. Intra-Area Prefix LSA (Type 9)
2. Link LSA (Type 8)
1. Router LSA can be split across multiple LSAs; Link State ID in LSA header is a fragment ID

IPv6 and IPv4 QoS Differences

Differences:

• There is no equivalent for match ip rtp in IPv6
• IPv6 access lists cannot be numbered

Differences between EIGRP for IPv4 and IPv6

1. Configured on interface
2. Must no shut the routing process
3. 32-bit router ID
4. Passive interface
5. Route filtering: only distribute-list prefix-list
6. Automatic summarisation
7. Cisco IOS support: 12.4(6)T
8. No auto-summary, as there is no classful concept anymore

IPv6 Neighbour Discovery Lifetime

The value indicates the usefulness of the router as a default router on this interface.Setting the value to 0 indicates that the router should not be considered a default router on this interface.

ipv6 nd ra lifetime superseded the old ipv6 nd ra-lifetime interface command.

IPv6 Neighbor Discovery Protocol

Types and Codes:

• Router Solicitation: 133
• Router Advertisement: 134
• Neighbor Solicitation: 135
• Neighbor Advertisement: 136
