[Xorp-users] Xorp 1.5 can't add multicast vif

[Pavlin Radoslavov]

For the record, I just committed the fix to CVS:

Revision  Changes                               Path
1.13      +16 -8;  commitid: 619348acd86d41a7;  xorp/config/acipmrt.m4
1.295     +13 -5;  commitid: 619348acd86d41a7;  xorp/configure

Please let me know if it works for you
(assuming you are still using the code from CVS ;)
