WAN Load Balance 1921 ISR

vetsnowit1 · ‎02-07-2013

So I can fail over my NAT and IPSEC VPN (DPD). I am curious can I load balance my WAN links too? Or am I just expecting too much?

I have a route map that is used for fail over, I just can't quite think how I would load balance the links

ip nat inside source route-map 10mb interface GigabitEthernet0/1 overload

ip nat inside source route-map efm interface Vlan3 overload

ip route 0.0.0.0 0.0.0.0 213.38.xx.xx

ip route 0.0.0.0 0.0.0.0 46.226.xx.xx 10

access-list 175 deny ip 172.16.20.0 0.0.0.255 172.31.114.0 0.0.0.255

access-list 175 permit ip 172.16.20.0 0.0.0.255 any

route-map 10mb permit 10

match ip address 175

match interface GigabitEthernet0/1

route-map efm permit 10

match ip address 175

match interface Vlan3

Hi,

you can load-share per source-destination IP with CEF switching( default) if you have 2 static routes for same prefix with same AD

Alain,

That is pretty helpful. I also looked at

Going to have a read out CEF and see which one suits best
