Team,
I have the following problem and Cisco (two engineers) so far is not
able to point the root of the problem see below, but the problem is that from
the minute I enable redistribute static or connected on the bgp connection all
traffic going to the Internet get hit with a delay 100ms versus the typical
9ms
10.21.32.0----Router1
--- ASA1---ATT ISP
|
----BGP-------
|
Level
3 ISP
|
---BGP---------
|
Router2---ASA2---ABOVE
ISP
There
is static default route
on router1 towards ASA1
NAT is
happening on ASA1
Router 1
and Router 2 are BGP
neighbors with Level 3
The ping
from 10.21.32.0 towards internet takes
approximately 9ms
When
10.21.32.0 network is redistributed into BGP on router1
the ping
takes 100ms +
and router1
becomes inaccessible sometimes
traceroute
from PC shows that delay has been included in journey from PC to ATT ISP
traceroute from asa does not shows a delay....
see below some traceroutes
