Therefore, for a flipped interface, no bgp fast-external-fallover is recommended . After the interface is shut down, the BGP session and neighbor relationship will remain until Switch(config)# interface vlan 10 Route tag: A tag that distinguishes between internal routing protocol routes and external routing protocol routes. Management distance ( Administrative Distance , referred to as the AD ) Gateway redundancy technology Non-default (manually configured non-default) priority and cost unchanged --------------- 192.168.10.1 Next Hop The PC has obtained the address and viewed dhcp snooping bingding databsae on SW1 : BGP comes in 1 and other routes are 20 , and the metric between OSPF remains unchanged. Beta All devices in a VLAN are in the same broadcast domain, and different VLANs are different broadcast domains. The concept of traditional IP routing Let us review: When the router receives an IP packet, check the IP header of the packet, and take the destination IP of the packet to the routing table for comparison according to the longest matching principle. Finally, Forward the packet. Therefore, traditional IP routing can only be routed based on the purpose of the data. Match ip address matches the access list or prefix list The following uses an example to illustrate the application of SSAP and DSAP . Assuming that Terminal System A and Terminal System B are to use a connection-oriented and reliable data transmission service, the following process occurs: Do not advertise to any peer (well-known community) Do not export to next AS (well-known community) (for forwarding delay), this TC will last for 35s ( 20+15 ) Switchport port-security mac-address sticky 00b0.1111.2222 *>i10.1.23.0/24 S uppercase S , stale , indicating expired routes Interface loopback0 Paths: (2 available, best #2, table Default-IP-Routing-Table) Not advertised to any peer The status of STP is as follows: 2 : RIP-2 ; Ip route 172.16.0.0 255.255.0.0 192.168.23.3 Underline, matching any separator such as ^ , $ ,ccnp route książka, space, tab , comma, { , } DHCP Snooping Binding Database Router bgp 345 The configuration is as follows: * The next hop of the route advertised by the device is 0.0.0.0) Store the result of the CRC cyclic redundancy check For R2 , it is now in its own process 1 , while learning the route of this OE2 from R1 and R3 , how will it choose? Review Configuration Revision 17 Type of verification: Determine if the frame has a VLAN tag . R3 announces 192.168.1.0 , 2.0 , and sets the community attribute of 1.0 to no-adv. The router goes to update the route of 3.0.0.0 Router bgp 300 the Next-Hop recursive This (recursive next hop ) broke the characteristics of the traditional hop-hop interface must be directly connected under the router IP restrictions. Recursive next-hop may not be directly connected to the network, as long as the relevant routes in the routing table are reachable. Generally, the recursive next-hop is unreachable, and the data will be handled by the route (generally the default route is matched).
