i'm having an issue trying to configure OSPFv3 between RB4011 and CRS309.
the two routers are directed connected by a 10G fibre. the RB4011 is switching and routing, and for now the CRS309 is only doing switching, across multiple VLANs, and that is all working fine.
i've configured OSPFv2 and that also works fine. expected LSAs are visible on both routers, routes from the RB4011 appear in CRS309's routing table.
now i'm trying to configure OSPFv3, but this isn't working. the RB4011 can see the CRS309, but the v3 neighbour entry is stuck in 'Init'. the CRS309 does not see the RB4011 as a v3 neighbour at all.
i checked with ROS packet sniffer. the R4011 is sending its own OSPFv3 traffic, and is receiving OSPFv3 traffic from the CRS309. however, on the CRS309, packet sniffer does not show any traffic at all from the RB4011 with protocol 89.
configuration of CRS309 (running ROS 7.10.1):
Code: Select all
/routing ospf instance
add disabled=no name=lf-v2 originate-default=never redistribute=connected,static router-id=10.1.2.15
add disabled=no name=lf-v3 originate-default=never redistribute=connected,static router-id=10.1.2.15 version=3
/routing ospf area
add disabled=no instance=lf-v2 name=backbone-v2
add disabled=no instance=lf-v3 name=backbone-v3
/routing ospf interface-template
add area=backbone-v2 disabled=no interfaces=vlan102
add area=backbone-v3 disabled=no interfaces=vlan102
Code: Select all
/routing ospf instance
add disabled=no name=lf-v2 originate-default=if-installed redistribute=connected,static,vpn router-id=10.1.2.1
add disabled=no name=lf-v3 originate-default=if-installed redistribute=connected,static,vpn router-id=10.1.2.1 version=3
/routing ospf area
add disabled=no instance=lf-v2 name=backbone-v2
add disabled=no instance=lf-v3 name=backbone-v3
/routing ospf interface-template
add area=backbone-v2 disabled=no interfaces=vlan102
add area=backbone-v3 disabled=no interfaces=vlan102
CRS309 does not have any firewall configured at all.
could someone please point out what i'm doing wrong, or maybe suggest next steps for troubleshooting? (i am quite new to OSPF, so it's entirely possible i've configured something wrong... no suggestion is too silly.)
