Hold timer is a matching parameter — the smallest is chosen. This example shows that the ESR after matching
set 30 seconds:
ESR1# sh mpls ldp discovery detailed
...
Targeted hellos:
1.1.1.1 -> 4.4.4.4:
Hello interval: 2 seconds
Transport IP address: 1.1.1.1
LDP ID: 4.4.4.4
Source IP address: 4.4.4.4
Transport IP address: 4.4.4.4
Hold time: 30 seconds
Proposed hold time: 30/45 (local/peer) seconds
If after matching, the Hello interval is greater than the Hold timer, then the Hello interval will be equal to Hold
timer/3.
ESR routers have the possibility to flexibly configure Hello holdtime, Hello interval and Keepalive holdtime
parameters: the parameters can be set for the entire LDP process, as well as for the corresponding neighbor.
Example output for the LDP process:
ESR# sh running-config mpls
mpls
ldp
router-id 1.1.1.1
keepalive 160
discovery targeted-hello holdtime 30
discovery targeted-hello interval 10
exit
exit
Example output for a targeted-LDP session for a particular neighbor:
ESR# shrunning-config mpls
mpls
ldp
router-id 1.1.1.1
neighbor 4.4.4.4
keepalive 160
targeted
discovery targeted-hello holdtime 30
discovery targeted-hello interval 45
exit
exit
exit
