12.3.1 Algorithm for setting Hello holdtime, Hello interval and Keepalive holdtime for the LDP process
1 Configure the LDP (see section LDP configuration)
2 In the LDP configuration mode,
set Hello holdtime
esr(config-ldp)#
discoverytargeted-hello
holdtime <TIME>
<TIME>— time in the range of [3..65535] seconds
Default value: 45
3 In the LDP configuration mode,
set Hello interval
esr(config-ldp)# discovery
targeted- hello interval
<TIME>
<TIME>— time in the range of [1..65535] seconds
Default value: 5
