Hola ...
I have a doubt, about the IEWB solution in Lab 3 Vol III Task 5.4 and
Task 5.5
In Task 5.4 R1 also advertise R2 Vlan 2 Route route to R5, so IMHO a
Distribute list should be applied to the outbound of R1 to R5 ??
Or it does not matter?
R1#
router bgp 100
***
neighbor 136.1.15.5 distribute-list 2 out
***
access-list 2 deny 136.1.2.0 0.0.0.255
access-list 2 permit any
Rack1R5#show ip bgp 136.1.2.0
BGP routing table entry for 136.1.2.0/24, version 5
Paths: (1 available, best #1, table Default-IP-Routing-Table)
Advertised to non peer-group peers:
4.4.4.4 136.1.15.1 136.1.57.7
300 300 300
136.1.245.2 from 136.1.245.2 (2.2.2.2)
Origin IGP, metric 0, localpref 100, weight 100, valid, external, best
And for Task 5.5 In my crazy world I did the following
R2#
router bgp 300
***
neighbor 136.1.245.5 route-map PREPREND:AS:PATH out
****
Rack1R2#show route-map PREPREND:AS:PATH
route-map PREPREND:AS:PATH, permit, sequence 10
Match clauses:
Set clauses:
as-path prepend 300 300
Policy routing matches: 0 packets, 0 bytes
But the solution show the use of conditional Advertisement but to be
honest, right now I can not see why the network 136.1.23.0/24 is
advertised in BGP
Thanks for your invaluable input
Victor.
