6. (Optional) Specify whether to create dynamic IP interfaces on top of MPLS major

interfaces and optionally what profile to use for them.

host1(config)#mpls create-dynamic-interfaces ip on-major-interfaces profile v4intf

LDP Global Tasks

Typically, you do not configure anything for LDP at the global level, but you can perform

the following optional tasks.

1. (Optional) Enable LDP and topology-driven LSP. Any LDP-related command creates

LDP implicitly, negating the need to issue this command.

host1(config)#mpls ldp

2. (Optional) Configure the redistribution of IGP routes to LDP.

host1(config)#mpls ldp redistribute ospf route-map boston5

3. (Optional) Configure a global LDP profile that specifies how long an LSR maintains

link hello records before another link hello is sent, the interval between link hellos,

or both.

host1(config)#mpls ldp interface profile ldp1

host1(config-ldp)#hello hold-time 55

host1(config-ldp)#hello interval 10

4. (Optional) Configure lists of peer addresses that targeted hello messages are sent

to or accepted from.

host1(config)#mpls ldp targeted-hello send list 10.21.5.87

host1(config)#mpls ldp targeted-hello receive list 192.168.45.25

NOTE: The mpls ldp targeted-hello receive list command is unnecessary if you configure

the mpls ldp targeted-hello send list command.

5. (Optional) Configure the hold time and interval values for targeted hello messages

used in LDP extended discovery.

host1(config)#mpls ldp targeted-hello holdtime 90

host1(config)#mpls ldp targeted-hello interval 30

6. (Optional) Configure LDP session retry values.

host1(config)#mpls ldp session retry-time 2

host1(config)#mpls ldp session retries 1800

7. (Optional) Configure the period that LDP negotiates with its peer for which the LDP

session is maintained in the absence of any LDP messages.

host1(config)#mpls ldp session holdtime 1800

8. (Optional) Configure the interval at which LDP sends session keepalive messages.

host1(config)#mpls ldp session keepalive-time 180

9. (Optional) Specify an IP address to be advertised to peers as the transport address

in discovery hello messages.
