Hi all, Thanks Ondrej for giving insights to my previous query. Your guess as to the neighbor AS having low hold time was correct and when I reduced keep-alive time on my end, I could bypass the Hold timer expired issue. I write this mail to address another query of mine. Is it possible to configure multicast routing protocols like igmp/pim through BIRD. I saw on the future work page that support for multicasting protocol is yet to be added to BIRD, also couldn't find the protocol implementation in the source code still wanted to confirm. If the support is not added can I make use of some other already supported routing protocol to address the issue? I want the server on which BIRD is configured to listen to mcast data. Also, on researching I could find out this thesis <https://is.cuni.cz/webapps/zzp/download/130183774> Do we plan to in-coporate these changes into BIRD anytime soon? Thanking you, Dhruv Bhagadia.
