Hi all,
i have some problem regarding BGP table convergence. There are two router (ASR1K and CRS-3) which have a direct interface and peering with loopback0 adresses.
The BGP Peering is established, and prefixes are transfered. However, from ASR1K to CRS-3 the convergence is very slow. The CRS-3 only learnes about 200 prefixes/s. The other direction CRS-3 to ASR1K works as apected, BGP full table is transfered within 30s. This is the output on ASR1K. MTU-Path-Discovery is enabled on both routers.
ASR1K#sh ip bgp neighbors x.x.x.x
BGP neighbor is x.x.x.x, remote AS xxxx, internal link
Description: CRS-3
Inherits from template BGP-TEMPLATE for session parameters
BGP version 4, remote router ID x.x.x.x
BGP state = Established, up for 2d17h
Last read 00:00:23, last write 00:00:02, hold time is 180, keepalive interval is 60 seconds
Keepalives are temporarily in throttle due to closed TCP window
Does anybody have an idea about this?
Best Regards
Marco
