LDP LSR IPv6 Operation with 32-bit LSR-ID

Consider the setup shown in Figure 1.

Figure 1. LDP Adjacency and Session over IPv6 Interface

LSR A and LSR B have the following LDP parameters.

LSR A:

• Interface I/F1 : link local address = fe80::a1

• Interface I/F2 : link local address = fe80::a2

• Interface LoA1: IPv4 address = <A1/32>; primary IPv6 unicast address = <A2/128>

• Interface LoA2: IPv4 address = <A3/32>; primary IPv6 unicast address = <A4/128>

• local-lsr-id (config>router>ldp>interface-parameters>interface>ipv6) = interface LoA1; option 32bit-format enabled

  LDP identifier = {<LSR Id=A1/32> : <label space id=0>}; transport address = <A2/128>

• local-lsr-id (config>router>ldp>targeted-session>peer) = interface LoA2; option 32bit-format enabled

  LDP identifier = {<LSR Id=A3/32> : <label space id=0>}; transport address = <A4/128>

LSR B:

• Interface I/F1 : link local address = fe80::b1

• Interface I/F2 : link local address = fe80::b2

• Interface LoB1: IPv4 address = <B1/32>; primary IPv6 unicast address = <B2/128>

• Interface LoB2: IPv4 address = <B3/32>; primary IPv6 unicast address = <B4/128>

• local-lsr-id (config>router>ldp>interface-parameters>interface>ipv6) = interface LoB1; option 32bit-format enabled

  LDP identifier = {<LSR Id=B1/32> : <label space id=0>}; transport address = <B2/128>

• local-lsr-id (config>router>ldp>targeted-session>peer) = interface LoB2; option 32bit-format enabled

  LDP identifier = {<LSR Id=B3/32> : <label space id=0>}; transport address = <B4/128>
