Hello all,
I have to deploy a router with two WICs, one's using 3G (HSPA+) network, and another one's using LTE network.
Here is the scenarios I thought about:
cellular 0/0/0 is LTE, cellular 0/1/0 is 3G
---Failover between two interfaces---
ip route 0.0.0.0 0.0.0.0 cellular0/0/0 1
ip route 0.0.0.0 0.0.0.0 cellular0/1/0 10
---Failover using ip sla---
Ip sla 100
icmp-echo 8.8.8.8 source-interface cellular0/0/0
frequency 10
Ip sla schedule 100 life forever start-time now
Track 1 rtr 100 reachability
ip route 0.0.0.0 0.0.0.0 cellular0/0/0 1 track 1
ip route 0.0.0.0 0.0.0.0 cellular0/1/0 10 name 3G_Backup
----------------------------------------
Which one's a better way of doing this? Would both solutions work? I thought about using ip sla in case the interface stays up.
Your idea would be much appreciated.
Thanks.

JP,
Either of these should work, and the sla would be better if the interface stays in an up/up state but doesn't pass traffic for whatever reason. I would go with the sla route to cover both scenarios (interface is up/up but not passing traffic OR interface is completely down).
HTH,
John

Thanks John. I wanted to verify it with someone
