[c-nsp] IS-IS on L3 vlan interfaces

[Vitkovsky, Adam]

That makes sense as ISIS p2p adjacency is initialized by rx of a ISHs through the ES-IS protocol followed by the exchange of the IIH

I was trying to figure out the mac layer mechanism difference between the p2p and lan and your post helped me to fill in the gaps
Thanks a bunch Olga

One time we had the same issue  -first wth p2p command configured (removed this command and adjacency came up), and second  -we added p2p command to broadcast link and adjacency came up. Both times the problem was with juniper filtering   -we used transit provider.

the point is that MAC addreses for Serial and LAN hello are different


The MAC-level broadcast addresses are:
      01-80-C2-00-00-15 for Level 2 adjacencies (AllL2ISs)
      01-80-C2-00-00-14 for Level 1 adjacencies (AllL1ISs)
  
The MAC-level point-to-point addresses are:
      09-00-2B-00-00-04 (AllEndSystems)     
      09-00-2B-00-00-05 (AllIntermediateSystems)
