MPLS crs3xx 7.1rc1

Sat Aug 28, 2021 12:10 am

Greetings friends, I'm trying to close mpls with another vendor but I couldn't establish an ldp session, is the MPLS package functional in this version?

Basic IPv4 LDP sessions should be functional. Post your config, maybe there is a misconfiguration.

@mrz thanks for the answer below are the settings I made based on the 6x version, OSPF is already running between peers


/ip address
add address=172.16.239.251 interface=loopback network=172.16.239.251
add address=172.16.224.30/30 interface=vlan21-p2p network=172.16.224.28

#OSFP
/routing ospf instance
add name=ospf-instance-1
/routing ospf area
add instance=ospf-instance-1 name=backbone
/routing ospf interface-template
add area=backbone interfaces=vlan21-p2p networks=172.16.224.28/30 type=ptp
add area=backbone interfaces=loopback networks=172.16.239.251/32

#MPLS

/mpls interface
add disabled=no interface=all mpls-mtu=1508
/mpls ldp
add disabled=no hop-limit=255 lsr-id=172.16.239.251 path-vector-limit=255 transport-addresses=172.16.239.251
/mpls ldp interface
add accept-dynamic-neighbors=yes disabled=no hello-interval=5s hold-time=15s interface=vlan21-p2p transport-addresses=172.16.239.251

I can establish an LDP session with a similar config. Please generate supout file and send it to support.

The same happens on my CHR lab:
chr-lab.png
When I enable LDP instance between two routers, traffic stops, however the label stack seems good for the first look.

The config is:
[admin@rtr1.CPE] > routing/ospf/export 
# sep/02/2021 11:42:10 by RouterOS 7.1rc2
# software id = 
#
/routing ospf instance
add name=ospfv2 router-id=10.0.10.11
add name=ospfv3 router-id=10.0.10.11 version=3
/routing ospf area
add instance=ospfv2 name=backbone4
add instance=ospfv3 name=backbone6
/routing ospf interface-template
add area=backbone4 interfaces=ether2
add area=backbone6 interfaces=ether2
add area=backbone4 interfaces=Loopback0 passive
add area=backbone6 interfaces=Loopback0 passive
[admin@rtr1.CPE] > mpls/export 
# sep/02/2021 11:42:12 by RouterOS 7.1rc2
# software id = 
#
/mpls interface
add interface=all mpls-mtu=1500
/mpls ldp
add disabled=yes distribute-for-default=yes lsr-id=10.0.10.11 transport-addresses=10.0.10.11 use-explicit-null=yes
/mpls ldp interface
add accept-dynamic-neighbors=yes disabled=no interface=ether2
[admin@rtr1.CPE] > ip address/export 
# sep/02/2021 11:42:15 by RouterOS 7.1rc2
# software id = 
#
/ip address
add address=10.0.1.2/30 interface=ether2 network=10.0.1.0
add address=10.0.10.11 interface=Loopback0 network=10.0.10.11
add address=10.0.11.1/29 interface=Loopback_VRF_A network=10.0.11.0
add address=10.0.12.1/29 interface=Loopback_VRF_B network=10.0.12.0
[admin@rtr1.CPE] >
The LDP and OSPF config is the same (except the IDs) on all links of CHR instances.
I running this lab in KVM with virtio interface emulation.

Should I send supout for support too?
