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?

router bgp 100
neighbor distribute-list 2 out

access-list 2 deny
access-list 2 permit any

Rack1R5#show ip bgp
BGP routing table entry for, version 5
Paths: (1 available, best #1, table Default-IP-Routing-Table)
 Advertised to non peer-group peers:
 300 300 300 from (
     Origin IGP, metric 0, localpref 100, weight 100, valid, external, best

And for Task 5.5 In my crazy world I did the following

router bgp 300

neighbor 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 is advertised in BGP

Thanks for your invaluable input
