The MX104 has a notoriously slow PPC-based RE unfortunately.

Hello:

I'm running two Juniper MX104s. Each MX has 1 ISP connected running
BGP(full routes). iBGP is running between the routers via a two port 20G
lag. When one of the ISPs fails, it can take upwards of 2 minutes for
traffic to start flowing correctly. The router has the correct route in the
routing table, but it doesn't install it in the forwarding table for the
full two mins.

I have a few questions if anyone could answer them.

   - What would a usual convergence time be for this setup?
   - Is there anything I could do speed this process up? (I tried
Multipath)
   - Any tips and tricks would be much appreciated

Thanks in Advance
