Hi All!
We operate a network with central router (linux), many vlan's and a lot of host routes:
% ip r l
10.0.0.2 dev vlan823 proto static scope link src 10.0.0.1
10.0.0.4 dev vlan908 proto static scope link src 10.0.0.1
10.0.0.5 dev vlan532 proto static scope link src 10.0.0.1
10.0.0.6 dev vlan901 proto static scope link src 10.0.0.1
10.0.0.7 dev vlan535 proto static scope link src 10.0.0.1
10.0.0.8 dev vlan624 proto static scope link src 10.0.0.1
10.0.0.9 dev vlan509 proto static scope link src 10.0.0.1
10.0.0.10 dev vlan605 proto static scope link src 10.0.0.1
. . .
10.0.0.34 dev vlan2853 proto static scope link src 10.0.0.1
. . .
Proxy-arp is used on the router. No IP address were assigned to vlan### interfaces.
Now we need to set up multicast routing between multicast source on eth5 and all these
vlan's. XORP refuses to work with this configuration - it says:
[ 2010/11/09 12:45:07.110947 TRACE xorp_igmp MLD6IGMP ] mld6igmp_process: RX
IGMP_V2_LEAVE_GROUP from 10.0.0.34 to 224.0.0.2 on vif vlan2853
[ 2010/11/09 12:45:07.110982 WARNING xorp_igmp MLD6IGMP ] RX IGMP_V2_LEAVE_GROUP from
10.0.0.34 to 224.0.0.2 on vif vlan2853: source must be directly connected
Can anybody please suggest a solution without total renumbering?
With best regads,
Ilya Ovchinnikov
