I have a customer utilizing private AS number 65100 when attaching to MPLS Carrier A.
The customer decides at each location he wants to add a second router and a second carrier for redundancy - and also wants to utilize the same private AS number (65100) when attaching to MPLS Carrier B.
The CE's would only be utilizing network statements through eBGP to advertise subnets to each carrier and only run one way redistribution from eBGP to the IGP at each location.
Would there be any circumstance why Carrier B could not accomodate AS 65100 on their network - even if another customer is already utilizing AS 65100 on Carrier B's network?
I am very certain that two seperate customers can utilize the same private AS number on Carrier B's MPLS network. Please advise if I am correct (or not).
