Hi guys.I have several ACLs configured on my N9K. I see a lot of 'fragmented' entries like these: [0x0472:0x0474:0x0474] permit tcp 0.0.0.0/0 x.x.x.x/26 fragment routeable 0x1 [0]It always comes together with 'normal' entries like these:[0x0473:0x047...

I guess the main reason is that TCP session between two LDP neighbors does not necessarily need to be established on the same link that Hello messages are send on. Refer to the topology on the picture I attached. Let's say we are establishing LDP bet...

Thank you, but it didn't help. How exactly should it help? I mean, MST sends its messages untagged, and, if I understand right, your configuration restricts any untagged traffic at all.

Switch is not sending BPDUs back in native VLAN (different from vlan 1)
