If OSPF VPN multi-instance is deployed on a Multi-VPN-Instance CE (MCE), routes cannot be calculated based on Type3, Type5, or Type7 LSAs with the DN bit. Therefore, OSPF detects routing loops when calculating routes. In this case, the vpn-instance-capability simple command is used to disable OSPF routing loop detection and enable OSPF to calculate routes based on received LSAs without checking the DN bit and route-tag in the LSAs. The route-tag is restored to the default value 1.

Check ospf peer on CE, if the tag for the peer is 1. Checking on the PE, the tag for this ospf peer should be 1 too.

OSPF-TE is an extension to OSPF extending the expressivity to allow for traffic engineering and use on non-IP networks.[21] Using OSPF-TE, more information about the topology can be exchanged using opaque LSA carrying type-length-value elements. These extensions allow OSPF-TE to run completely out of band of the data plane network. This means that it can also be used on non-IP networks, such as optical networks.

OSPF-TE is used in GMPLS networks as a means to describe the topology over which GMPLS paths can be established. GMPLS uses its own path setup and forwarding protocols, once it has the full network map.

In the Resource Reservation Protocol (RSVP), OSPF-TE is used for recording and flooding RSVP signaled bandwidth reservations for label switched paths within the link-state database.

The title is "The tag of ospf peer impact ospf routing learning", but actually you shared us is just part of the ospf process and router ID, could you tell us more details about how ospf working on huawei Cloud engine switches.

OSPF routing protocol is a link-state routing protocol for Internet Protocol (IP) networks. The protocol uses the internal gateway protocol (IGP) of link state routing algorithm.

Thanks for your sharing, normally, the OSPF is a very important protocol and very common, so the logs are also very important for checking the issue of OSPF, this post is very good for us to understand the logs, thanks again
