hello all. i'd like to confirm the following proposal before telling a customer the scenario is doable. a customer wishes to have a primary internet T1 connection, and a backup cable modem. i've been reading the PDF for reliable static routing and would like to make sure i can acheive the following config (i haven't tested it in a lab):
ip sla monitor 1
type echo protocol ipIcmpEcho 1.1.1.1 source-interface serial 0/1/0:0
timeout 1000
threshold 2
frequency 3
!
!
ip sla monitor schedule 1 life forever start-time now
!
track 50 rtr 1 reachability

!
interface Serial0/1/0:0
description - T1 connection -
ip address 1.1.1.2 255.255.255.252
!
interface FastEthernet0/0

ip route 0.0.0.0 0.0.0.0 1.1.1.1 track 50
ip route 0.0.0.0 0.0.0.0 FastEthernet0/0 254
!
access-list 100 remark ACL to trigger PBR
access-list 100 permit icmp any host 1.1.1.1 echo
!
route-map PBR permit 10
match ip address 100
set ip next-hop 1.1.1.1
set interface Null 0

ip local policy route-map PBR
