5)  Verify your configurations 

After you complete the above configurations, PE 1 and PE 2 should be able to ping each other. 

z 

Site 1 and Site 2 belong to the same VPN. Site 1 accesses the network through PE 1 in AS 100 and 

Site 2 accesses the network through PE 2 in AS 600. 

z 

PEs in the same AS runs IS-IS between them. 

z 

PE 1 and ASBR-PE 1 exchange labeled IPv4 routes by MP-IBGP. 

z 

PE 2 and ASBR-PE 2 exchange labeled IPv4 routes by MP-IBGP. 

z 

PE 1 and PE 2 are MP-EBGP peers. 

z 

ASBR-PE 1 and ASBR-PE 2 use their respective routing policies and label the routes received 

from each other. 

z 

ASBR-PE 1 and ASBR-PE 2 use MP-EBGP to exchange labeled IPv4 routes.
