WAN Failover with a dynamic ip address

[John Peterson]

Hi,

I currently have one interface which get its ip address via the DHCP and under the interface the cmd is ip address DHCP setroute.

In which case when setting up isp failover the procedures requires the command "route outside 0.0.0.0 0.0.0.0 XXX.XXX.XXX.XXX. 1 track 1"

the problem is I don't know the next hop ip address.

Is there any way around this?

Thanks

Hi,

if your interface is a point-to-point like hdlc or ppp or frame-relay point-to-point or a dialer interface then you can specify the interface instead of next-hop.

next-hop is only mandatory for multiaccess interfaces like ethernet or frame-relay physical or multipoint subinterface.

By the way i think you can discover next-hop with a sh ip route static or you could do a traceroute.

Regards.

Alain.

Hi,

ip route 0.0.0.0 0.0.0.0 track 1

will solve your issue.

Thanks,

But the I'm using a ASA 8.2 which does not allow a Default gateway via exit interface,

Also I'm using virgin media and the default gateway always changes.

Hi,

isn't the route already installed by DHCP? sh route static will tell you if so then just create another route outside with a higher AD going to the backup link to the next-hop you should know  about.
