I need some advice and help on the best way to construct proper routing for a DS3 MPLS circuit. The DS3 is replacing all my P2P T1's. Right now, I run OSPF for me LAN & P2P WAN's. 6509 is my core and I deploy 1751V & 2811's at the WAN. The HQ end of the P2P T1's are into 2621. The 2621's will go away when the circuit is moved to the DS3 and terminated into the 6509.
The 6509 OSPF is:
router ospf 1
network 172.20.0.0 0.0.255.255 area 0
network 192.168.0.0 0.0.255.255 area 0
The 192.168.xx s are my data VLANs and the 172.20.xx are for Voice. I will be constructing QoS maps to tag the traffic. I will be running Voice across DS3 to remotes.
The remotes OSPF is simple:
ip address 192.168.255.250 255.255.255.252
service-module t1 clock source internal
service-module t1 remote-alarm-enable
service-module t1 fdl att
router ospf 1
network 192.168.255.248 0.0.0.3 area 0
(The F/E interface is 192.168.13.254)
The ISP wants to run BGP on the MPLS and based on the parameters they provided I came up with the followng for the remote router.:
router bgp 65000
network 172.20.13.0 mask 255.255.255.0
neighbor xx.xx.xx.xx remote-as 12345
neighbor xx.xx.xx.xx version 4
neighbor xx.xx.xx.xx soft-reconfiguration inbound no auto-summary
I assume that the xx.xx.xx.xx will be the IP that the ISP will provide.
The network statements are the internal subnets I need to route.
I guess I am confused as to what is needed. I was always taught not to mix interior and exterior routing protocols. But I want to utilize them to avoid coding static routes. So I need to ensure that all the routes are know at the core and the remotes. any suggestions and examples would be appreciated. I have never worked with BGP before....
