Then when PC1 receives this Gratuitous ARP , because the senderIP conflicts with itself, then a bubble pops up locally (if it is R4 has two BGP neighbors, where R3 is its federated IBGP neighbor and R5 is its federated EBGP neighbor. ! Solution: The way to redistribute static summary route to avoid the sub-optimal routing and other issues LocPrf Locally find a route to the neighbor and try TCP three-way handshake. Waiting for completion, the authentication is completed during TCP setup. If the TCP connection is not up, enter the Active state and try to connect repeatedly. Update it; however, it does not send its secondary address 11.0.0.0 segment from fast0/0 to R1 (unless the split horizon is turned off). Switch(config-if)# ip address 192.168.20.254 255.255.255.0 Router bgp 345 The prefix list contains the serial number, matching from the smallest Etc., then there is a prioritization between these methods: network>redistribute>aggregate Note that this principle is not used as a BGP routing routing policy.

In other words, for multiple paths, the MED is compared only if the first AS in AS_SEQUENCE is the same ; any leading AS_CONFED_SEQUENCE will be ignored. MED only affects traffic between directly connected autonomous systems, and does not pass across ASs. "Double-point bidirectional" routing re-release is a simple model that can often be used in large networks. For example, in a financial network, if a dynamic routing protocol is run between a secondary line and a branch router, then this model may be involved. The so-called two-point bidirectional refers to a node with two routes re-issued on the boundary of two routing domains, and the direction of re-distribution is bidirectional. For example, in the above figure, the secondary line has two aggregation routers for access to the following outlets or branch routers. Then the two routers are two-point. In addition, in order to make the routes of the entire network reachable, two-way routing re-distribution is deployed on the two routers, that is, OSPF is re-released to RIP ,ccnp r&s resume, and RIP is also re-released to OSPF. .
