[j-nsp] j series query not answered on the KB

[Nick Ryce]

Hi there,

I have predominantly used cisco and have recently forayed into the land of juniper and have the following question regarding a J2320 with junos 9.

I have a j2320 with a 100meg metro ethernet connected on interface 0 with a /30 link subnet (for example 10.0.0.0./30) this is also the default gateway.
Interface 1 is connected to a 10meg metro Ethernet with a /30 link subnet (10.0.1.0/30).

What I am looking to do is have everything go across the 100meg link and if that goes down then route through the 10 meg.  The only problem is that on interface 0 the link may not show as down as the provider connection is through a switch and the fibre behind that may break.

In cisco land I would use object tracking and set up a rule to ping the default gateway on interface 0 and when that became unreachable then it would automagically failover.

The juniper kb gives reference to track-ip but it doesn't seem to be avail on j series routers.

Any help appreciated.

Nick
