Hi Carlito,
You almost certainly want them in the same table.
As I said, if you do this:
ping 8.8.8.8 source wan1
then the ping packet will be constructed with a source address from wan1, but
it will still follow your routing config for transmission. This means that if
you have:
ip route add 0.0.0.0/0 via 172.78.10.158 wan0
then the packet will be sent on wan0 but with wan1's source, the upstream
could/should reject this due to a uRPF check.
You might lobby the community, or perhaps add yourself, a 'send via
interface,nexthop' option to ping.
Regarding redundancy, if you configure ECMP;
ip route add 0.0.0.0/0 via 172.78.10.158 wan0
ip route add 0.0.0.0/0 via <NH> wan1. /// or perhaps your DHHCP server
gives you this
then the FIB will react to the state of the links. When one is down only the
other will be used. You can also configure BFD if you peer supports it and FIB
can use this for link state monitoring.

Hi Balaji,
As far as I know, VPP doesn't have link monitoring to switch routes.
But as you said, I added a cron job to check link status and switch
routes on failure.
I added each interface route to a particular FIB table. This way I am
able to use ping 8.8.8.8 source wan0 or wan1.
Is this the correct way?
Thanks!
