Step | Description | Command | Keys |
---|---|---|---|
1 | In the context of MPLS parameters configuration, specify the interfaces involved in the MPLS switching process | esr(config-mpls)# forwarding interface { <IF> | <TUN> } | <IF> – an interface's name, specified in the form described in Section Types and naming order of router interfaces; <TUN> – the name of the tunnel is specified as described in section Types and naming order of router tunnels; |
2 | Specify the router-id for LDP (not necessary if transport-address is specified). | esr(config-ldp)# router-id <ID> | <ID> – router identifier, defined as AAA.BBB.CCC.DDD where each part takes values of [0..255]. |
3 | In the context of the address family ipv4 settings, specify transport-address (not necessary if router-id is specified). | esr(config-ldp-af-ipv4)# transport-address <ADDR> | <ADDR> – defined as AAA.BBB.CCC.DDD where each part takes values of [0..255]. |
4 | In the context of the address family ipv4 settings, specify interfaces for enabling LDP process. | esr(config-ldp-af-ipv4)# interface { <IF> | <TUN> } | <IF> – an interface's name, specified in the form described in Section Types and naming order of router interfaces; <TUN> – the name of the tunnel is specified as described in section Types and naming order of router tunnels. |
5 | Enable LDP process. | esr(config-ldp)# enable | |
6 | Enable explicit-null functionality (optional). | esr(config-ldp)# egress-label-type explicit-null | |
7 | In the LDP neighbor configuration mode, set the password with the password command (optional). | esr(config-ldp-neig)# password {<TEXT> | ENCRYPTED-TEXT>} | <CLEAR-TEXT> – password, sets by string of [8..16] characters; <ENCRYPTED-TEXT> – encrypted password of [8..16] bytes ([16..32] characters) in hexadecimal format (0xYYYY...) or (YYYY...). |
The following functionality is also available as part of the LDP configuration:

---|---|---|---|
1 | Configure addressing and one of IGP on all P and PE routers. | ||
2 | Configure LDP transport tag distribution. | ||
3 | Create VRF. | esr(config)# ip vrf <VRF> | <VRF> – VRF instance name, set by the string of up to 31 characters. |
4 | Specify route distinguisher for the given VRF. | esr(config-vrf)# rd <RD> | <RD> – Route distinguisher value, specified in one of the following forms:
|
5 | Specify route target import for the given VRF. | esr(config-vrf)# route-target import <RT> | <RT> – Route-target value, specified in one of the following forms:
|
6 | Specify route target export for the given VRF. | esr(config-vrf)# route-target export <RT> | <RT> – route-target value, specified in one of the following forms:
|
7 | Specify the allowed number of routes for this VRF. | esr(config-vrf)# ip protocols <PROTOCOLS> max-routes <VALUE> | <PROTOCOL> – protocol type, may take following values: rip (only in global mode), ospf, isis, bgp; <VALUE> – amount of routes in the routing table, takes values in the range of:
|
8 | In the context of address-family VPNv4 BGP configuration, enable extended attribute transfer. | esr(config-bgp-neighbor-af)# send-community extended |
