About rtr.

Good day

Please can somebody help me with configuration example on rtr protocol.

Best regards

An example rtr config follows. This example uses rtr to check reachability of an IP address via ICMP. If the address is not reachable, the router then decrements the priority of HSRP on an Ethernet LAN interface. You can play around with the options, and if you let me know exactly what you are trying to accomplish, I can help further.

<----------SNIP----------->

rtr 1

type echo protocol ipIcmpEcho 192.168.254.1

request-data-size 1000

timeout 1000

threshold 500

frequency 5

rtr schedule 1 life forever start-time now

track 3 rtr 1 reachability

interface GigabitEthernet0/1

ip address 192.168.5.2

standby 1 ip 192.168.5.1

standby 1 priority 105

standby 1 preempt

standby 1 track 3

<------------SNIP--------->

You can use "show track", "show rtr config" (check "show rtr ?" for other options) and "show standby brief" to observe the effects of this configuration.

I need to configure backup link on broadcast (ethernet interface).We have 3 routers; RTA, RTB et RTC.

RTA is serie cisco 831

RTB is broband cisco UBR 7246 (but the interface cable of UBR 7246 can't support vrrp)

RTC is serie cisco 1710

RTA can reach RTC directly or via RTB.

the fist priority route will be via RTB and the second priority will be direct.

I need to configure it with rtr, beacuse hsrp and vrrp are not support by UBR7246 on interface cable.

thank you.

Stephane.

Stephane,

I think you can best use Policy Based Routing (PBR). See the following URL's:
