OSPF neighbour-ship on multi-ip P2P interface

[Santosh P K]

Naveeen,
     Did you test with /31 prefix configured on interface and did that work too? Could you also let me know which version of FRR you are using?

Thanks

Subject: OSPF neighbour-ship on multi-ip P2P interface

Hi,

     Does FRR OSPF support neighborship on an P2P interface with Multiple Interface IP addresses? I am using multiple 32bit host ip address on same interface.

     When I try to establish ospf neighborship on an P2P interface with multiple IP addresses assigned, OSPF neighborship keeps resetting due to, receival of interleaving hello of 1st or 2nd ip-address.   Is there any way to avoid this  and bring up sessions on the Interface.

    Above thing works good if the Interface IP addresses are assigned < 32 bit  subnet mask (for example, 10.0.0.1/24 instead of 10.0.0.1/32).

Regards
Naveen
