字段 长度 描述 IKE_AS Initiator SPI 8字节 发送者用来唯一标识一个IKE安全联盟,该值不能设置为0。 IKE_AS Responder SPI 8字节 应答者用来唯一标识一个IKE安全联盟,对于IKE初始交互的消息该值必须为0,其他消息不能为0。 Next Payload 1字节 仅随头部之后的负载的类型。
When GR or NSR is disabled, FIB entries must be retained for some time after a protocol process switchover or RIB process switchover. When GR or NSR is enabled, FIB entries must be removed immediately after a protocol or RIB process switchover to avoid routing issues. Perform this task to...

Before the router updates its RIPng routing table based on the received response, it must check the validation of the response packet, such as whether the IPv6 address is the link-local address, whether the port number is correct. The response packet failed the check will be discarded. 2.1...
address defined on the Bluetooth interface overrides the previously defined IP address. The IP address configured on the Bluetooth interface cannot be on the same subnet as the addresses configured on the In-Band interfaces. The IP address on the Bluetooth interf...
If the interface associated with this IP address is ever brought down, or if the address is removed, the OSPF process must recalculate a new router ID and resend all its routing information out its interfaces. If a loopback interface is configured with an IP address, the Cisco I...
Routing occurs at a sending TCP/IP host and at an IP router. In each case, the IP layer at the sending host or router must decide where to forward the packet. For IPv4, routers are also commonly referred to as gateways.To make these decisions, the IP layer consults a routing table ...

to report an error in datagram processing. For such purposes, this protocol, the Internet Control Message Protocol (ICMP), is used. ICMP uses the basic support of IP as if it were a higher level protocol; however, ICMP is actually an integral part of IP and must be implemented by every...
