MPLS VPNs - MPLS VPN Configuration - Configuring MP-BGP Between PEs
4 important questions on MPLS VPNs - MPLS VPN Configuration - Configuring MP-BGP Between PEs
How much iBGP relationships are needed between to PEs for MP-BGP?
Only one iBGP neighbor relationship
What commands need to be configured on PE for MP-BGP?
PE1(config-router)#neighbor x.x.x.x remote-as 65001 (iBGP)
PE1(config-router)#neighbor x.x.x.x update-source lo0
PE1(config-router)#address-family vpn4
PE1(config-router-af)#neighbor x.x.x.x activate
PE1(config-router-af)#neighbor x.x.x.x send-community
Why is the command neighbor x.x.x.x update-source lo0 neccassary for MPLS VPNs?
