Currently only CLNP Ip cef 0x18B7 Understand the establishment process of LDP neighbor relationships. In the standard SPF algorithm, there can be multiple equivalent paths to the same destination. We call it ECMP ( Equal-cost Multipath ). ! *Aug 18 04:37:06.239: Tun Sender: 1.1.1.1 LSP ID: 20 ! When the change attribute (path bandwidth), using Make Before Break manner Types of. The 7th bit is an internal / external flag, set to 0 to indicate an internal metric, and 1 to be an external metric. Let's look at an example: BoS Ip cef *Aug 18 09:06:07.919: Controlled Load Service break bit=0 service length=0 Type 9 flooding range only on this link 0 interfaces: The third layer destination IP matches the packet with the same specific prefix.

After the neighbor is discovered, the one with the highest transmission address is the active initiator. Note that here,ccna course content, the TCP handshake packet, the source address is the local Transport Address , and the destination address is the transport address of the peer . The transport address is the LDP Router-ID of the router by default . Therefore, it must be ensured that the two Transport Addresses are reachable.
