How to apply EBGP load balacing between Multi-VRF MPLS core PE with 6 sub-interface interconnect to PE of IP core network ? The PE of MPLS core is have 2 physical 10GE link connect to PE of IP core & each 1 physical have 3 logical-dot1q subinterface for separate traffic of 3 VRF MPLS VPN service. 2nd physical link is used for enhance redundancy & reliability. Now..2 physical have 6 logical sub interface, 6 subnet /30 ip ptp to opposite PE. 2 logical sub in the different physical has binded to 1 VRF..that mean 6 sub binding to 3 VRF. In the MPLS core use MP-BGP with private AS number & advertise route to IP core network by eBGP, that IP core network have a real public AS number. In the PE of IP core have 6 logical-sub & 2 physical link too but not run MPLS. How I can apply the solution for separate traffic of 3 VRF for monitoring & 2 physical , 2 logical-sub for 1 VRF is load balance (that mean all of 2 physical , 6 logical-sub for 3 VRF)? (6 neighbour peering to ip point to !
point? or apply EBGP multihop with loop back address & add existing 2 IGP equal cost do load balancing? How I can do this ?
Because 1 PE router is binding in 3 VRF MPLS VPN but opposite PE router not have VRF MPLS VPN !!! then... but if we decided for apply peering EBGP multihop with
static route to loopback address via to ptp next-hop with 2 equal cost. What the number of loopback interface is required for handle EBGP load balance for 3 service (1 loopback or 3 loop back need ? ,Where ??? both PE or only some site? if only 1 site ..what is PE must apply?) In the Cisco... I'm not sure about limitation for BGP process & limitation of maximum-link (maximum-path) for load sharing & limitation for configuring BGP update source loopback interface? Can configure more than 1 update source loopback interface in the diffrent peer but same destination AS number? & In MPLS PE ...Loopback interface need for apply in to the different VRF or not.. If no need ..can see it ?. & In the VRF can use the diferrent BGP update source with different loopback? Finally... how i can configure & control about incomming & outgoing traffic EGBP load balancing between MPLS core to IP core?
Thanks you very much.
