strange behaviour with load sharing multicast mode

[sebastan_bach]

hi all i am having a clusterXL over splat NGXR65.i am running it on load sharing multicast mode. i have only 2 intefaces on the splat so i have configured eth1 as the snyc interface and on eth0 i have configured 2 vlans . vlan 10 for the internal network and vlan 20 for the external network.

as per the documentation when traffic is generated by the cluster members the source ip will always be the virtual ip address of that segment.

here my internal virtual cluster ip address is 10.1.1.254 and external virtual ip is 1.1.1.254.

the problem is when i ping from the gateway to any external network the source is properly taken by 1.1.1.254 as it should.

but when i ping to any internal network from the gateway the source ip is taken by one of the cluster member interface ip.

is this because i am using both the vlans on the same interface ??.

has anyone faced this issue before???

regards
