Segment routing display commands
SR Linux supports display commands to provide operational information about segment routing, including the following:
- SID database
- label block information
- tunnel-table entries
Displaying the SID database
Use the info from state command to display information about the SID database.
--{ candidate shared default }--[ ]--
# info from state network-instance default segment-routing mpls sid-database
network-instance default {
segment-routing {
mpls {
sid-database {
prefix-sid 10.20.1.1/32 sid-label-value 3010 protocol isis protocol-instance 0 protocol-multi-topology 0 algorithm 0 {

}
}
Displaying label block information
Use the info from state command to display information about the configured label blocks.
--{ * candidate shared default }--[ ]--
# info from state system mpls label-ranges
system {
mpls {
label-ranges {
static {
name srgb-range-1
start-label 16001
end-label 16999
allocated-labels 10
free-labels 989
status ready
}
}
}
}
}
Displaying tunnel table entries
Use the show network-instance default tunnel-table command to display information about segment routing tunnel table entries. You can adjust the output of the report to filter by address type, encapsulation type, tunnel type, and destination prefix.
Show all tunnels
--{ running }--[ ]--
# show network-instance default tunnel-table all
