[f-nsp] IPv6 OSPFv3 Brocade to Cisco

[Howard, Christopher]

I’m having trouble getting OSPFv3 up between a Brocade ICX7750 and a Cisco 4500X.  I’ve found on cisco-nsp where someone else found a working config using the following:

Brocade side:

ipv6 ospf authentication ipsec spi #### esp sha1 KEY

Cisco side:

 ipv6 ospf authentication null
 ipv6 ospf encryption ipsec spi #### esp null sha1 KEY

Well, I’m already doing OSPFv3 between Brocades using the exact line in the example, which is good.  I also have OSPFv3 neighbors up with our firewall (not Cisco).  However, when I use the Cisco side of the example I don’t get a successful neighbor.  On the Brocade side, I see a neighbor in the neighbor table, but it’s stuck in INIT state.  On the Cisco side, the neighbor table is empty.

Normally when it’s stuck in INIT state, I’d check MTU sizes and general connectivity between both sides.  Both are 1500 bytes and both sides can ping each other.

Does any one have any ideas as to what I can look at next, or if they have a working config that’s different from mine?  I can’t remove the authentication without having to clear that out of my network everywhere.
