Juniper J2320 Redundancy and failover

Asked by nwteam in Network Routers, Internet Service Providers (ISP), Network Design & Methodology

Hi Guys/Girls.


Need a bit of advice on the best way to set this system up.

I have some servers that require redundant networking.

I have a pair of Juniper J2320's running J9.6 Junos. I have two seperate BGP feeds coming in via ethernet.

All switches are extreme networks layer 2 devices.

My initial thought was to use the Juniper virtual chassis system to link the two J2320's together. The problem with that is that it requires 3 ports on each router to be used up, one for management(fxp0), one for control of the cluster(fxp1), and one for the data fabric(FAB) they use to forward packets to each other.

That leaves me with one port free. That means the one port has to handle the two bgp feeds, and the tagged vlan's from my servers/switches.

If that itself doesn't seem like a problem, is there any issues with using the redundant ethernet interface function of the cluster to swap the two bgp, and tagged vlans from primary to secondary if the router goes down?


Or should I be looking at a different way of doing things?
