When the public network tag is LDP only , for cross-domain VPN-optionC scenario 2, a three-layer tag is required in the packet forwarding process.

For the cross-domain VPN-OptionB approach, an MP-eBGP neighbor relationship needs to be established between the two ASBRs.

For the cross-domain VPN-OptionA mode, the route passed between the two ASBRs is a normal IPv4 route.

For the cross-domain VPN-OptionB approach, two ASBR-PEs are interconnected with multiple interfaces (including sub-interfaces), each associated with a VPN, each ASBR PE treats the peer as a CE.

Sub-VLAN is used to isolate broadcast domains

A Super VLAN can contain one or more Sub-VLANs

The super Sub-VLAN contains a physical interface that can establish a Layer 3 VLANIF interface

Sub-VLAN contains a physical interface that can establish a Layer 3 VLANIF interface

After modifying the original Stub area to a Totally Stub area, the number of LSAs in the LSDB of each router in the region will definitely be reduced

ASBR cannot be present in either the Stub zone or the Totally Stub zone

When you modify the original Stub area to a Totally Stub region, the number of LSAs propagating within the region will definitely decrease

If there are two ABR in the Totally Stub zone, each ABR sends an LS ID of 0000 to the router in the zone LSA

LSDB

R1, which exists in both Level-1 and Leve-2, can ping the interface address of R2 loopback0

R there is a route to R2 loopback0 10022/32

No neighbor relationship can be established between R1 and R2

ASBR-Sunmary-LSA is allowed to be published to the NSSA region

AS-External-LSA is allowed to be published to the Stub region

Any OSPF zone can be configured as a special zone

Zone can be equipped with zhiyi

NVE interface

VXVAN L2 Gateway

VXLAN L3 Gateway

VLANIF interface

The system distinguishes between static BFD sessions and dynamic BPD sessions by dividing the identifier area Dynamically assign this landmark identifier

BFD sessions can only be established dynamically

Static configuration of BFD session refers to manual configuration of BFD session parameters through the command line, including local identifiers and remote identifiers

Router HW's next hop router does not have a path to the destination address

Ping is successful, but congestion occurs on the path to the destination address

ICMP packets can reach the destination address But the destination device failed to reply

Router HW does not have a legitimate route to the destination address

There is a firewall in the remote destination network, and no ICMP traffic is allowed
