Hello, I do have some confusion about which one is better for IPv6 in Service Provider networks as far as IP routing and MPLS application is concern! 1. Which protocol should i use to support the IPv6 in network: ISIS or OSPFv3? As ISIS has multi-topology feature that can give us capability to run IPv4 network separate from IPv6 right! and same thing with OSPF: OSPFv2 will be used for IPv4 routing and OSPFv3 will be used for IPv6 routing! again Its look like resource utilization for both the protocol will be same as they are going to use separate database for storing the routing or topology information. ISIS still has advantage over OSPF as it does use the TLV structure which can help in expanding network to support the new feature! 2. MPLS is not distributing label for IPv6 protocol so again there will not be any IGP best path calcuated for any MPLS related application for IPv6! 3. what if i have already running OSPFv2 for IPv4 in the network then should i think for migrating to ISIS? if yes then what are the advantages that I can look at for migrating my network to IS-IS? regards Devang Patel
