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:

• LDP tag filtering configuration (see section MPLS technology management#LDP LDP tag filtering configuration);
• LDP session parameters configuration (see section MPLS technology management#Configuring Configuring session parameters in LDP);
• t-LDP session parameters configuration (see section Configuring session parameters in targeted-LDP).

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:

• <ASN>:<nn> — where <ASN> may take values [1..65535], nn may take values [1..65535];
• <ADDR>:<nn> — where <ADDR> specified as AAA.BBB.CCC.DDD/EE, AAA-DDD  may take values [0..255], nn may take values [1..65535];
• <4ASN>:<nn> — where <4ASN> may take values [1..4294967295], nn may take values [1..65535];

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:

• <ASN>:<nn> — where <ASN> may take values [1..65535], nn may take values [1..65535];
• <ADDR>:<nn> — where <ADDR> specified as AAA.BBB.CCC.DDD/EE, AAA-DDD  may take values [0..255], nn may take values [1..65535];
• <4ASN>:<nn> — where <4ASN> may take values [1..4294967295], nn may take values [1..65535];

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:

• <ASN>:<nn> — where <ASN> may take values [1..65535], nn may take values [1..65535];
