Hi All,
My name is Wei. When I was looking over "draft-ietf-mpls-static-yang-13", I=
found that there is no way to specify "next-hop" address in the out-segmen=
t for LSP. Is that the intended behavior?
For instance, If I want to add a static LSP to swap packets with incoming l=
abel "202" to outgoing label "203" and send to next hop address "192.168.1.=
49". There is no option to add that next hop address in draft-ietf-mpls-bas=
e-yang outsegment.
However, I see the option of adding next-hop address in the mpls-base, see =
example below:
{
"name":"RIB-MPLS",
"address-family":"ietf-mpls:mpls:mpls",
"routes":{
"route":[
{
"next-hop":{
"outgoing-interface":"eth0",
"ietf-mpls:mpls-label-stack":{
"entry":[
{
"id":1,
"label":24002,
"ttl":255
}
]
},
"ietf-ipv4-unicast-routing:next-hop-address":
"192.0.2.5"
},
"source-protocol":"ietf-rsvp:rsvp",
"ietf-mpls:mpls-enabled":true,
"ietf-mpls:mpls-local-label":24001,
"ietf-mpls:destination-prefix":"24001",
"ietf-mpls:route-context":
"RSVP Src:198.51.100.3,Dst:198.51.100.4,T:10,L:1"
}
]
}
}
Thanks.
