IPv6 Deployment: IS-IS vs OSPF

What are the pros and cons, is-is vs ospf, with regard to IPv6 deployment? Would greatly appreciate your insights. Thanks.

Hi,

OSPF MIB is not supported for the 8540CSR when you deploy the same for IPV6.

Re: IPv6 Deployment: IS-IS vs OSPF

"Standard" OSPF--OSPFv2--actually doesn't run IPv6--you have to run OSPFv3, which is a completely seperate protocol, process, etc. You can redistribute between the two, but the OSPF working group in the IETF has pointedly decided that there's no reason to provide any other mechanism for migrating from OSPF with IPv4 to OSPF for IPv6 other than ships in the night or redistribution at some edge. There are other changes to OSPFv3 that don't relate to IPv6 directly, as well.

IS-IS carries both protocols in the same process/packets, although it still runs seperate SPF trees for them, etc.

So, a lot is going to depend on whether you prefer implementing IPv6 routing in a seperate protocol, or in the same protocol, with a different database.
