Hello Folk,
In a lab I was doing I, there were multiple BGP AS#s. All the BGP
routers were speaking to each other. There were no problems with
routing or anything ... my question is related to some show commands I
saw. Here goes:
PE1#show ip route 10.131.96.0
Routing entry for 10.131.96.0/24
Known via "bgp 100", distance 200, metric 0
Tag 200, type internal
Last update from 10.131.31.242 4d22h ago
Routing Descriptor Blocks:
* 10.131.31.242, from 10.131.31.255, 4d22h ago
Route metric is 0, traffic share count is 1
AS Hops 1, BGP network version 0
Route tag 200
@ the bottom of this you will see the tag 200. This was learned from a
bgp AS # 200. There was no tagging set (please do not ask for configs)
... This is a MPLS lab / network ... I would not think that this would
make a difference ...
Is this normal... BGP 'auto tagging' of routes learned from different AS
numbers?
Kindest regards,
Andrew
