Routes advertised from VPNv4 Peer Metric.

Hi,

I have BGP VPNV4 peer router ,1st is Edge RTR and 2nd Route Reflector.

TOPOLOGY: CUSTOMER ====(multiple path)====RR-----------EDGE RTR

We are using IGP underneath. Now, Im received routes from Route reflector then install to Edge RTRs VRF but when I look at the bgp table, Router metric is changed to IGP metric. BGP inherited the IGP metric.

EGDE RTR#sh bgp vpnv4 unicast vrf test 10.22.23.0/24

Paths: (2 available, best #1, table test)

Not advertised to any peer

(65 64 651) 655 650 354 1, imported path from xxxx:10.122.203.0/24

13.21.22.7 (metric 65) from 3.3.3.11 (3.3.3.11) <<<--------

Origin IGP, metric 0, localpref 100, valid, confed-internal, best

Extended Community: xxxxxx

mpls labels in/out nolabel/2408

(65 64 651) 655 1 1 1, imported path from xxxxxxx

13.16.4.11 (metric 70) from 3.3.3.11 (3.3.3.11) <<<-------- I want to prefer this route

Origin IGP, metric 0, localpref 100, valid, confed-internal

Extended Community: xxxxxxx

mpls labels in/out nolabel/10066

What is the best solution for this better if the changes will afftect on EDGE RTR. t

Thanks
