Trying to configure extended admin groups on JUNOS 24.2R1-S2.5.
set routing-options admin-groups-extended-range minimum 32
set routing-options admin-groups-extended-range maximum 4294967295
set routing-options admin-groups-extended R1_R2 group-value 100
set routing-options admin-groups-extended R1_R5 group-value 666666
set protocols mpls interface ge-0/0/0.0 admin-group-extended R1_R2
set protocols mpls interface ge-0/0/2.0 admin-group-extended R1_R5
To my amusement, with this config it didn't advertise the actual admin groups (IS-IS sub-TLV 14), but SRLG:
SRLG neighbor: R2.00, Numbered interface
IP address: 10.100.1.1
Neighbor's IP address: 10.100.1.2
IDs: R1_R2
SRLG neighbor: R5.00, Numbered interface
IP address: 10.100.3.1
Neighbor's IP address: 10.100.3.5
IDs: R1_R5
Also when IS-IS database is redistributed into BGP-LS, JUNOS advertises extended admin group in TLV 1096 (SRLG) instead of 1173 (EAG).
When Cisco IOS-XR (with "extended-admin-group ietf" config), JUNOS correctly interprets it in "show isis database extensive" output:
IS extended neighbor: R1.00, Metric: default 10 SubTLV len: 163
Local interface index: 4, Remote interface index: 333
IP address: 10.100.1.2
Neighbor's IP address: 10.100.1.1
IPv6 address: 2001:100:1::2
Neighbor's IPv6 address: 2001:100:1::1
Administrative groups: 0 <none>
Maximum bandwidth: 1000Mbps
Maximum reservable bandwidth: 10Gbps
Current reservable bandwidth:
Priority 0 : 10Gbps
Priority 1 : 10Gbps
Priority 2 : 10Gbps
Priority 3 : 10Gbps
Priority 4 : 10Gbps
Priority 5 : 10Gbps
Priority 6 : 10Gbps
Priority 7 : 10Gbps
Traffic engineering metric: 500
Ext Admin Group: 0
Ext Admin Group: 0
Ext Admin Group: 0
Ext Admin Group: 0
Ext Admin Group: 0
Ext Admin Group: 0
Ext Admin Group: 0x100
Ext Admin Group: 0
However, JUNOS doesn't redistribute this value into BGP-LS.
Is there any config that enables RFC7308 support on JUNOS? Either for IS-IS, or for BGP-LS (ideally both).
Cheers,
Dmytro
