Howto failover to alternate default gateway on pppoe failure
CentOS server has 2 ethernet ports(eth0 and eth1).
eth0: connected to switch and then to internet
eth1:connected to adsl modem and running rp pppoe through it and creates ppp0
I want default gateway to be through ppp0 when ppp0 is up (this happens - as the setting for gateway in rp pppoe is enabled).
However when ppp0 goes down then default gateway to revert to eth0. This does not happen.
