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

[Patrik Olsson]

Hello!

1. There is a standard which even Cisco supports called BFD. That tracks
routes from all protcols including static routes. So if the other end
supports BFD, that settles it.

2. Dynamic routing using OSPF/ISIS/BGP?

3. Junos scripting. Run ping checks and change static route based on result.


Cheers
Patrik

> 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.
