ccnp route 300-101 bgp

R5 performs link redundancy. However, at this moment, R5 can only go to the target network through R2 . 100 The TAG value is set when the originating ASBR generates an external LSA . If the external LSA is re-advertised to other OSPF autonomous systems, the TAG value is carried by default. In CEF , there are two main types of load balancing, based on messages and based on purpose. Both R1 and R2 inject 100.0.1.0 and 100.0.2.0 into BGP using network . RIP Version 2 Carrying Additional Information 100 i Sw(config)#vlan 201 PBR Case 8 bits When the routing policy changes, the neighbor is requested to re-advertise the route ( BGP does not periodically send updates) LocPrf Associate route-map when route is re-published Peer group Distance bgp xyz //x is the EBGP route, y is the IBGP route, and z is the BGP route announced by the local network . AS_CONFED_SEQUENCE and AS_CONFED_SET Ip community-list 11 permit 100:11 no-export ? Match tag matches based on the tag of the route Use ip community-list to match the community value 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. //The details are not released. Generally seen between switches or between switches and routers and servers R3 No synchronization no auto-summary FastEthernet0/0 C 10.1.12.0 is directly connected, Serial0/0 [Experiment 7 ] There are subnet routes (no match); there are default routes The route originated from the local route (such as the local network or aggregate ), that is, the next hop is 0.0.0.0 ( in the BGP table , the next hop of the route advertised by the current router is 0.0.0.0) If you turn on always-compare-med Bgp fast-external-fallover Of course, it is ok to filter the prefix list in the in direction on R2 . Border Gateway Protocol (BGP) Connected Invalid timer OSPF , but R3 ignores this route (locally configured with a static summary route pointing to null0 ), although the LSA is still passed to R5 , which means that although R5 still has a 1.0.0.0/8 route, the packet After being thrown to R3 , it is finally discarded at R3 , so there is still a problem here. Status codes: s suppressed, d damped, h history, * valid, > best, i - internal, r RIB-failure, S Stale ? SwitchA hangs Various types of ports of a Layer 3 switch The Auto interface is willing to be a trunk . If the adjacency interface is set to trunk or desirable ,ccnp route 300-101 bgp, the interface becomes a trunk. So to rule 12 : if multiple path originating router IDs or router IDs are the same, then the shortest path of the Cluster-List is preferred .

Ge ge-value Ip dhcp snooping vlan 10 Interface fast0/1 A sends the BPDU out of its designated port, and the BPDU is flooded to the network. Spanning-tree 100 For details on the BGP neighbor table field, see the show section of the BGP Configuration section of this document. Solution 1 , modify the default AD value of BGP so that its EBGP route AD value is greater than RIP to achieve the preferred purpose, but this solution may not be appropriate, because he will have an impression on all BGP routes, if only hope for 1.1.1.0 And 2.2.2.0 has an impact? RIP-2 Only R3 configuration is as follows Route summary technology background Match comprising 100 and 200 of AS_PATH (Don't be surprised, the author's record is an afternoon, personally complete the debugging task of nearly 100 switches, of course, there are integrator brothers to help put equipment, add points, labeling). After the switches are debugged, they will be installed in the various computer rooms or weak rooms of the customer site. After all the switches are properly put into operation, they will be put into operation.
