Hello,
I am labbing with an 9300v (10.3(1)) and some XRv boxes, trying to have the not ldp 9300v talk to the rest of the ldp boxes.
I was thinking of having one of the XRv boxes act as a mapping server, so that the 9300v could receive the prefix-sids mapped to the loopbacks of the rest of the ldp routers.
The configuration of the mapping server is:
router isis basnet
net 49.0001.0000.0707.0701.00
address-family ipv4 unicast
segment-routing mpls
segment-routing prefix-sid-map advertise-local
(this router has 7.7.7.1/32 as loopback interface and 16007 as sid)
and for the prefix-sid-map...
segment-routing
mapping-server
prefix-sid-map
address-family ipv4
1.1.1.1/32 1
3.3.3.1/32 3
5.5.5.1/32 5
9.9.9.1/32 9
However, the 9300v is only able to see the SID of the XRv it is directly connected to, but not those mappings:
nxos9k-21# show isis segment-routing sids
SID database for ISIS-basnet VRF default
SID Prefix Flags
7 7.7.7.1/32
21 21.21.21.1/32 local
I have another XRv box connected to this same mapping server, and all those SIDs are present:

16007 7.7.7.1/32
16009 9.9.9.1/32
16021 21.21.21.1/32
What I have noticed is that the XRv is able to recognize those sid bindings ...

Does anyone know if I could be missing something in the configuration of the 9300v?
