Hi,
I have tried the same scenario with gobgpd and gobgp and the result is same. I
guess sending each of the l3vpn-ipv4-unicast route in a separate update is the
default method although sending the ipv4-unicast routes is not same. Its packs
routes in a single updates.

Hi Iwase,
I have tried to send multiple routes for with the same rd and same attributes.
But its sends the update in multiple bgp updates. I expect to group prefixes
with the same RD and attributes (RT, local pref etc) in a single bgp updates.
Is this the supposed behaviour?
mpls := bgp.NewMPLSLabelStack(100)
rd := bgp.NewRouteDistinguisherTwoOctetAS(1,1)
ecommunities := []bgp.ExtendedCommunityInterface{
bgp.NewTwoOctetAsSpecificExtended(bgp.EC_SUBTYPE_ROUTE_TARGET, 1, 1, true),
}
nlri1 := bgp.NewLabeledVPNIPAddrPrefix(32, "11.0.0.1", *mpls, rd)
mplsattrs1 := []bgp.PathAttributeInterface{
bgp.NewPathAttributeOrigin(0),
bgp.NewPathAttributeExtendedCommunities(ecommunities),
bgp.NewPathAttributeMpReachNLRI("192.168.1.1",
[]bgp.AddrPrefixInterface{nlri1}),
}
nlri2 := bgp.NewLabeledVPNIPAddrPrefix(32, "11.0.0.2", *mpls, rd)
mplsattrs2 := []bgp.PathAttributeInterface{
bgp.NewPathAttributeOrigin(0),
bgp.NewPathAttributeExtendedCommunities(ecommunities),
bgp.NewPathAttributeMpReachNLRI("192.168.1.1",
[]bgp.AddrPrefixInterface{nlri2}),
}
//send the update
if _, err := s.AddPath("", []*table.Path{table.NewPath(nil, nlri1, false,
mplsattrs1, time.Now(), false),table.NewPath(nil, nlri2, false, mplsattrs2,
time.Now(), false)}); err != nil {
log.Fatal(err)
}

This the update from the router, multiple prefixes in a single update.

Hi Iwase,
Sorry for late update. It was holiday in here :). And also thanks for the
sample code. I was lost in AddPath function in the server.go. Tried to use in
the native way but it seems it only has subfunction for EVPNNLRI’es. And then
no time dig more. Again great thanks for help. It save me lots of time. Also
Thanks Dale for the reply.
I have added router-target extended community to the code you have send.
gobgp<https://github.com/osrg/gobgp/tree/3645e7dee68faff9bd4fbadbb47dc89ecd06058a>/packet<https://github.com/osrg/gobgp/tree/3645e7dee68faff9bd4fbadbb47dc89ecd06058a/packet>/bgp<https://github.com/osrg/gobgp/tree/3645e7dee68faff9bd4fbadbb47dc89ecd06058a/packet/bgp>/helper.go
helped me lot.

Hi Deniz and Thanks Dale!
"gobgp/cmd/global.go" does similar, but it might be too complex.
https://github.com/osrg/gobgp/blob/master/gobgp/cmd/global.go#L1147-L1177
The following snippet helps for you?
mpls := bgp.NewMPLSLabelStack(100)
rd := bgp.NewRouteDistinguisherTwoOctetAS(65000, 100)
// Or, if you prefer to get RD from string;
// rd, err := bgp.ParseRouteDistinguisher("65000:100")
// if err != nil {
// return nil, err
// }
nlri := bgp.NewLabeledVPNIPAddrPrefix(24, "10.0.0.0", *mpls, rd)
attrs := []bgp.PathAttributeInterface{
bgp.NewPathAttributeOrigin(0),
bgp.NewPathAttributeAsPath([]bgp.AsPathParamInterface{
bgp.NewAs4PathParam(bgp.BGP_ASPATH_ATTR_TYPE_SEQ, []uint32{65002, 65001}),
}),
bgp.NewPathAttributeMpReachNLRI("192.168.1.1", []bgp.AddrPrefixInterface{nlri}),
}
path := table.NewPath(nil, nlri, false, attrs, time.Now(), false)
Thanks,
Iwase

I am tring to use gobgp for just announcing l3vpn-ipv4-unicast routes
stored in database, some blackhole routes for different user profiles.
Can you give me an example how can I add some l3mpls vpn path like the
one in the /GoBGP as a Go Native BGP library./
I can give you some pointers: It looks like the GoBGP constructors for route
objects closely parallel the structure of routes inside BGP. So look at
https://tools.ietf.org/html/rfc3107#page-3 for how MPLS labels are attached to
prefixes, and https://tools.ietf.org/html/rfc4364#section-4.2 for how route
distinguishers are used.
I see in
github.com/osrg/gobgp/packet/bgp/bgp.go<http://github.com/osrg/gobgp/packet/bgp/bgp.go>
constructors like func NewLabeledVPNIPAddrPrefix and a lot of lines containing
"MPLS".
