I have 2 SRX240s in a cluster and I utilize the UTM and IDP features. Per all the base config documents, I have a "Routing-Group 0" and a "Routing-Group 1" (RG1 contains all the RETHs)
Because, with UTM and IDP, both RG0 and RG1 must be active on the same node at all times to route traffic (currently running 10.4R6).
Can I just eliminate RG1 all together and place all the RETHs into RG0? I don't have an extra cluster to test this on. I can test after hours, but wanted to possibly save a drive in.
