IOS XR and ipv6

Post by seany » Thu Mar 30, 2017 10:09 pm

Hi

Is there any none issue with ipv6 with xr ? I get this error *Mar 30 21:59:26.916: %OSPFv3-4-AREA_MISMATCH: OSPFv3-1-IPv6 Received packet with incorrect area from FE80::5200:FF:FE06:1, Ethernet0/0, area 0.0.0.14, packet area 0.0.0.13. Config is correct, but somehow it mismatches with different Area.

regards

Sean

Using a bridge with more than 2 nodes will trigger STP...
To permit flooding, you need to use dedicated link between nodes

Current Eve Bridge implementation is like that:

Bridge conn < 3 -> no spanning tree, flooding ok
Bridge conn > 2 -> spanning tree, flooding stopped
