<small>Hi,<br>
<br>
I have found the issue in my configuration and now able to perform
PUSH/SWAP/POP operations for MPLS via Linux Kernel.<br>
<br>
And I tested the same with FRR and here I am not sure about the
configuration for popping a MPLS label.<br>
<br>
To add label via zebra,<br>
<b><font face="Courier New">ip route 192.168.133.0/24
192.168.200.3 label 100</font></b><br>
<br>
To swap label via zebra,<br>
<b><small><small><font face="Courier New, Courier, monospace"><big><big>mpls
lsp 100 192.168.123.4 200</big></big></font></small></small></b><br>
<br>
To remove label via zebra,<br>
<b>?????</b><br>
</small>
<div class="moz-cite-prefix"><small><br>
Please let me know the configuration if anyone knows.<br>
<br>
Thanks,<br>
Vijayalaskhmi<br>
<br>
PS:<br>
The issue observed with Linux configuration of static route with
nexthop as IP address works fine but nexthop as interface (dev)
does not work.<br>
<br>
As the following works fine,<br>
<small><font face="Courier"><b>192.168.123.0/24 encap mpls 100
via 192.168.200.3 via 192.168.200.3 dev ens9<br>
<br>
</b></font></small>but this does not work,<br>
<small><font face="Courier"><b>192.168.123.0/24 encap mpls 100
via 192.168.200.3 dev ens9<br>
<br>
<br>
</b></font> </small></small></div>

<small>Hi Kishore,<br>
<br>
Thanks for your reply.<br>
<br>
I tried the same with Linux MPLS via iproute2 configuration.
Still the behavior is same.<br>
So it is clear that the issue is not with FRR.<br>
<br>
Let me fix the issue in my Linux kernel and get back to you if I
need any support.<br>
<br>
Regards,<br>
Vijayalakshmi<br>

style="font-size:7.5pt">Hello,<br>
<br>
We are currently working with simulating a PE router in
MPLS architecture.<br>
We run zebra and ldp with below configuration<br>
and facing issues in swapping and popping of label in
zebra.<br>
<br>
In my MPLS table I have the following entries,<br>
<br>
</span><span
style="font-size:7.5pt;font-family:"Courier
New"">zebra_2# show mpls table<br>
Inbound Outbound<br>
Label Type Nexthop Label<br>
-------- ------- --------------- --------<br>
16 LDP 192.168.100.2 3<br>
17 Static 192.168.100.2 18</span><span
style="font-size:7.5pt"><br>
<br>
But still zebra is not swapping the label and also not
forwarding the received traffic (</span><span
style="font-size:10.0pt">inbound label 16/17)</span><span
style="font-size:7.5pt"> to the respective nexthop.<br>
<br>
Is there any special command to activate mpls
configuration ?<br>
Can someone help us in a configuring zebra MPLS to pop
label and swap label</span>?<span style="font-size:7.5pt"><br>
<br>
Thanks,<br>
