Hello
Seeking help for routing issue,
Primary route for R3 to reach R1 is via SP
Backup route for R3 to reach R1 is via R2
When backup link is up then packet drop is noticed from R3 to R1
R2----------------R3---------(service_provider)-------------R1
R2-----------------------------(service_provider)-------------R1
R3 is connected to R2 on a Point to Point Link
R3 reaches R1 using SP network
R2 reaches R1 using SP network
((( Router R3 )))
int fa 0/0
description Connected to R2
ip add 192.168.1.1 255.255.255.252
ip ospf cost 25
Int fa 0/1

Hello Ronald,
you can use a shaper for this outbound direction on both routers (if both are under your control)
policy-map shape-2Mbps
class class-default
shape average 2000000
int f0/0
service out shape-2Mbps
done on both ends
depending on platform and needs a child policy could be invoked to implement a queueing system (scheduler)
Hope to help

Hello Ronald,
compare sh ip route
you may be facing a problem when primary link is restored caused by non zero weight of locally injected routes into BGP
you can solve this using:
router bgp 8190
neigh 172.16.33.26 weight 40000
Hope to help

Thank You, it worked.
How can I restrict the Bandwidth to 2MB on fa 0/0 ( Total traffic in/out = 2MB )
