>For some reason BGP is leaking prefixes to IGP, or there's some problem >with the IGP deployment itself. Now I know reason because bgp goes into mpls route, we use also ibgp between our core router, and as you tell that mpls by default assign label every route learn IGP. What is way to stop learn by mpls of ibgp ??

I'd say anything with 'mpls' will also be useful. sh ip route summary IP routing table name is Default-IP-Routing-Table(0) IP routing table maximum-paths is 32 Route Source Networks Subnets Overhead Memory (bytes) connected 0 11 792 1584 static 2 1 216 432 ospf 1234 2 120 8784 17568 Intra-area: 24 Inter-area: 0 External-1: 0 External-2: 98 NSSA External-1: 0 NSSA External-2: 0 bgp 1234 136929 178004 22675176 46212920 External: 312639 Internal: 2294 Local: 0 internal 3663 8014644 Total 140596 178136 22684968 54247148 Removing Queue Size 0 This is extract of config: mpls ldp neighbor 10.0.0.11 labels accept LDP-MPLS mpls ldp discovery targeted-hello accept from LDP-MPLS mpls ldp advertise-labels for LDP-MPLS mpls label range 50 524000 mpls label protocol ldp router ospf 1234 log-adjacency-changes redistribute static subnets passive-interface Vlan1001 passive-interface GigabitEthernet2/1 passive-interface FastEthernet3/3 passive-interface FastEthernet3/5 passive-interface FastEthernet3/6 network 10.0.0.10 0.0.0.0 area 200 network XXX 0.0.0.3 area 0 network XXX 0.0.0.3 area 200 network XXX 0.0.0.3 area 200 network XXX 0.0.0.3 area 200 network XXX 0.0.0.3 area 0 network XXX 0.0.0.3 area 0 network XXX 0.0.0.15 area 200 network XXX 0.0.0.15 area 200 network XXX 0.0.0.15 area 200 network XXX 0.0.0.255 area 200 network XXX 0.0.0.3 area 200 network XXX.72 0.0.0.3 area 200 network XXX 0.0.1.255 area 200 default-information originate always router bgp 1234 no bgp enforce-first-as bgp log-neighbor-changes neighbor CUSTOMERS peer-group neighbor CUSTOMERS version 4 neighbor PEER-M peer-group neighbor PEER-M update-source FastEthernet3/6 neighbor PEER-M version 4 neighbor PEER-M-V6 peer-group neighbor PEER-M-V6 update-source FastEthernet3/6 neighbor PEER-M-V6 version 4 neighbor 10.0.0.11 remote-as 1234 neighbor 10.0.0.11 update-source Loopback0 neighbor 10.0.0.11 version 4 neighbor 10.0.0.12 remote-as 1234 neighbor 10.0.0.12 update-source Loopback0 neighbor 10.0.0.12 version 4 neighbor 10.0.0.14 remote-as 1234 neighbor 10.0.0.14 update-source Loopback0 neighbor 10.0.0.14 version 4 neighbor 10.0.0.15 remote-as 1234 neighbor 10.0.0.15 update-source Loopback0 neighbor 10.0.0.15 version 4 address-family ipv4 neighbor PEER-M remove-private-as neighbor PEER-M soft-reconfiguration inbound neighbor PEER-M prefix-list AS1234-OUT out neighbor PEER-M route-map M-IN in neighbor 10.0.0.11 activate neighbor 10.0.0.11 send-community both neighbor 10.0.0.11 next-hop-self neighbor 10.0.0.11 soft-reconfiguration inbound neighbor 10.0.0.11 prefix-list AS1234-OUT out neighbor 10.0.0.11 route-map IBGP-A-IN in neighbor 10.0.0.11 send-label neighbor 10.0.0.12 activate neighbor 10.0.0.12 send-community both neighbor 10.0.0.12 next-hop-self neighbor 10.0.0.12 soft-reconfiguration inbound neighbor 10.0.0.12 route-map IBGP-B-IN in neighbor 10.0.0.12 send-label neighbor 10.0.0.12 filter-list 1 out neighbor 10.0.0.14 activate neighbor 10.0.0.14 send-community both neighbor 10.0.0.14 next-hop-self neighbor 10.0.0.14 soft-reconfiguration inbound neighbor 10.0.0.14 prefix-list AS1234-OUT out neighbor 10.0.0.14 route-map IBGP-C-IN in neighbor 10.0.0.14 send-label neighbor 10.0.0.15 activate neighbor 10.0.0.15 send-community both neighbor 10.0.0.15 next-hop-self neighbor 10.0.0.15 soft-reconfiguration inbound neighbor 10.0.0.15 prefix-list AS1234-OUT out neighbor 10.0.0.15 route-map IBGP-D-IN in distance bgp 200 190 190 no auto-summary no synchronization network XX mask 255.255.240.0 network XX mask 255.255.254.0 exit-address-family Thanks very much Matteo _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
