If provided solution doesn't work we really appreciate if you can share the diagram of your network with IP scheme as I have in production network one Cisco and Huawei router and both are working fine with above (IP ospf network point-to-point & IP ospf mtu-ignore).

Please do not hesitate to leave the message in case of any further assistance.

My 5720Hi version is below:

Huawei Versatile Routing Platform Software
VRP (R) software, Version 5.170 (S5720 V200R010C00SPC600)

And my interface configuration:

interface GigabitEthernet0/0/24
undo portswitch
ip address 10.10.0.14 255.255.255.252
ospf network-type p2p
ospf enable 1 area 0.0.0.0

My problem is no peer to cisco device.

Btw, I get bad pkt rcvd on Cisco.

one possible reason I can think of is MTU mismatch.
check the MTU on both sides.

on Cisco side please do the following under interface.

ip ospf network point-to-point
ip ospf mtu-ignore

On huawei side you have to configure this in global view.

ospf (process ID)

area 0

network 10.10.0.14 0.0.0.0

and under the interface

ospf network-type p2p

This should work, if not please do not hesitate to leave the message.

Hi Muhammad,

Thanks for comments.

I have changed the network type to broadcast. As I mentioned before i get an error message on Cisco as "bad pkt rcvd".

I am sharing my huawei and cisco configs below,

Huawei:

interface GigabitEthernet0/0/24
undo portswitch
description "to-Abr1.thnlon.core-gi0/0/3"
ip address 10.10.0.14 255.255.255.252
ospf enable 1 area 0.0.0.0

ospf 1 router-id 10.10.1.1
area 0.0.0.0
network 10.10.0.12 0.0.0.3

Cisco:

interface GigabitEthernet0/0/3
ip address 10.10.0.13 255.255.255.252
ip ospf 1 area 0
speed 1000
no negotiation auto

router ospf 1
router-id 185.100.189.17
network 10.10.0.12 0.0.0.3 area 0

So no adjacency!!!!!!
