Hello,
In F5, a route domain is a configuration object that isolates network traffic. segment network traffic.
So if you have the same node in RD0, RD1 and RD2 it works without problems. it's just that the paths they take to reach node are not the same regarding your network configuration.
So in your case you have to validate that you set your configuraiton correctly:
- create RD1 and RD2 (assign the right vlan)
- Create default route for RD1 and RD2
default%1 --> Gateway Address xxx.xxx.xxx.xxx%1
default%2 --> Gateway Address xxx.xxx.xxx.xxx%1
Then it will works.
Just a last point when you process your tcpdump you have to do it from RD0 even if you want to trap request of other RD...
