OSPFv2 adjacencies per node

Is there any limitation on number of OSPFv2 adjacencies allowed per quagga node ? In my test a quagga node is taking only 20 adjacencies on different interfaces.


Thanks,
Rohan

Just a guess, but are you hitting IGMP mcast limit perhaps?

$ cat /proc/sys/net/ipv4/igmp_max_memberships
20

Add net.ipv4.igmp_max_memberships = XX to /etc/sysctl.conf.
