I have a R1 connected to WAN01 and WAN02 routers. Both WAN routers redistributing EIGRP routes from the Hub location and my R1 receving the route such as 172.16.1.0 via both WAN01 and WAN02.
I am going the change the metrics on WAN02
router bgp 65100
redistribute EIGRP 100 route-map CHANGE
no auto-summary
route-map CHANGE permit 10
match ip address 99
set metric 2142999 100 255 1 1500
access-list 99 permit 172.16.1.0 0.0.0.255
The question is by changing the metric on WAN02, my R1 will only receive 172.16.10 from WAN01, and will only install the same route from WAN02 when my WAN01 goes down. Will changing the metric effect on the actual bandwidth and delay of the interface when the traffic is pass through WAN02 to 172.16.1.0.
Thanks

Changing the metric does not have any affect on the actual throughput of the interfaces. It will not affect either. If you change the metric be aware that R1 will still receive the advertisement from WAN02 but it should prefer the route from WAN01.

Hi John,
Thanks for your quick reply. That exactly what I want. I want R1 to receive route from WAN02 as well, but doesn't want to be installed into a routing table until WAN01 goes down.
I just wanted to make sure that I don't introduce any latency by changing the metrics on WAN02 in a case WAN01 goes down and then WAN02 becomes a successor for the route to 172.16.1.10 from R1.
Thanks again !
