IPv6 iGP redistribution

Similarities to IPv4

• Redistribution takes routes from the IP routing table, not from the iGP databases.
• Route maps can be used for filtering, metrics, route tags.
• Admnistrative distance has not changed.
• Options to prevent routing loops; Administrative distance, route tags, filtering.
• Syntax is the same.

Differences to IPv4

• Supported “match” commands in route-maps vary on iGP
  • OSPF/RIP cannot match op “route-type” with a Route-map
    • EIGRP has no problems using “route-type”
  • Route-map matching IPv6 ACLs must have IPv6 prefix as source portion and “any” as destination of ACL.
• IPv6 redistribute connected does not include interfaces running the iGP;
  • redistribute include-connected
