Hello All,
I have an coreswitch in a facility. This coreswitch is the primary POP for all the Internet traffic. In the uplinks there are Internet Firewall and an Internet Router.
This is the metro link set up. Assume A is primary POP for Internet and B is primary POP for MPLS traffic and viceversa.
Questions:
1. There are BGP running between coreswitch and Internet router. If i give show IP route, the route is learned through external BGP.
Routing entry for 161.178.227.0/24
Known via "bgp 65420", distance 20, metric 0
Tag 65500, type external

Routing Descriptor Blocks:
* 203.99.192.22, from 203.99.192.22, 00:33:06 ago
Route metric is 0, traffic share count is 1
AS Hops 1
Route tag 65500
MPLS label: none
How does the route is learned, does it pass through the firewall and back back to core switch?
Thanks
