Hello everyone,
During some experiments with sr, sr-te and stuff tried to establish sr-te lsp that crosses two different areas. To try this, i`ve made a simple lab:
two areas, ibgp between A1-ABR1 <-> A2-ABR1 (they act as route reflectors) and ibgp sessions between A1-PE1 <-> A1-ABR1, A2-ABR1<->A2-PE1
BGP-LS enabled for this sessions.
Trying to build lsp from A1-PE1 (1.1.1.1) to A2-PE1 (4.4.4.4)
Configuration on A1-PE1:
show configuration protocols mpls
traffic-engineering {
database {
import {
l3-unicast-topology {
bgp-link-state;
}
policy ted-pol;
}
export {
policy ted-pol;
l3-unicast-topology;
}
}
}
cross-credibility-cspf;
root@A1-PE1> show configuration protocols source-packet-routing
compute-profile follow-igp {
metric-type {
igp;
}
}
source-routing-path test {
to 4.4.4.4;
primary {
pr_path {
compute {
follow-igp;
}
}
}
}
But lsp stays down:
root@A1-PE1> show spring-traffic-engineering lsp
Warning: License key missing; requires 'Segment Routing' license
To State LSPname
4.4.4.4 Down test
ted looks like ok to me:
root@A1-PE1> show ted link topology-type l3-unicast
