We have a similar setup as below and i am wondering how to monitor this backup circuit which is a point to point leased line
SiteA MPLS SiteB MPLS
Backup circuit between 2 sites
If any of the site MPLS is down it will automatically redirected to the backup via the other MPLS circuit
Can you let me know the best way of monitoring the backup circuit?
I would like to know if there is any issue with the backup circuit
I am sure some one will be monitoring the same king of setup using NPM
a good way to get around this issue is to use IPSLA as you must identify target and source for your testing. You can also integrate these "objects" onto your maps.
This is how we are getting around GRE tunnels always being up without keepalives as well.
