Hi,

 

I want know, in F5 bridge Mode using VLAN group - why we need to define self IP address.

And one more point here, why F5 self IP address is not coming while doing TRACEROUTE.

Because you have two separate vlans, so each VLAN requires a self-IP.

You may want to look at Virtual Wire which directly links two interfaces at Layer-2

With a VLAN Group, arp requests/responses get passed directly between the grouped VLANs, so there is no actual routing via the self-IP. Because of this, TRACEROUTE will not see the self-IP.

 

In general, VLAN groups should be used with care, as they may not always provide the results you expect or desire.

 

 

Thanks Blakely,

For kind response,

Actually I am using VLAN group and assign self IP to VLAN grp.

Does self IP required here?
