We inherited a network here which has an MPLS setup between three offices. All three of these offices do BGP with the ISP. I created an IPSEC vpn on an ASA in the 1 office. Most servers are in a second office. When I asked the ISP to add the route into the MPLS they stated I needed to simply advertise that route.
Currently it's not working an am looking for guidance. I have 2 Cisco 2801 routers as my edge device doing bgp.
on the office 1 I did an IP route 172.25.5.0 255.255.255.0 10.50.5.8 (10.50.5.8 = the next hop for the device - the asa doing the vpn) This works and the tunnel traffic gets there as you would expect it to if you traceroute from that office.
The problem is the route isn't advertising via BGP
under the router bgp I added network 172.25.5.0 as well to advertise as this is how the ISP instructed me to do it. I am afraid I simply do not know enough about BGP to guess any further. Am I missing something ? I was able to confirm no access list is being used to limit routes that get advertised. I was under the impression that when I do an IP route command that is all BGP needs to know that it should be advertised?
