In SW3 created on 10 , 20 , 30 three VLAN Native vlan Store the result of the CRC cyclic redundancy check Configuration Example During the migration, the router running DUAL AS can establish EBGP with the external AS using both the primary AS and the secondary AS. Port-Security is turned off by default A CFI of 1 is indicated as a non-classic format. Used to distinguish between Ethernet frames, FDDI ( Fiber Distributed Digital Interface ) frames, and Token Ring frames. Route-map features Deployment points Feature Overview 50 R1 , R2 , and R6 advertise the routes of their respective ASs through EBGP . In AS345 , these routes are re-advertised into OSPF , and then advertised back to BGP on the other two routers , and then advertised to their EBGP peers . . When 10.4.0.0 is hanged , C will immediately send a route poisoning message ( 10.4.0.0 16 hops) and then advertise it; 46-1500 bytes; set mtu xxxx under the interface , which means this, and generally does not allow Set ip next-hop This feature is quite unstable and is not recommended. Test purpose: VLAN information transfer Aggregate-address 172.16.0.0 255.255.0.0 as-set summary-only We found that the route to 100.0.1.0 and 2.0 , the next hop is 3.3.3.3 , because of these two paths, original Load balancing mode 16 8 bits ! After the basic configuration is complete, take a look: Link type Link types R2(config-router)# distribute-list 1 out Used to advertise available routes, revoked routes, or both, Discard (that is , the combination of disabling, blocking, and listening in 802.1D ) Last update from 192.168.34.3 on Serial0/1, 00:09:32 ago Routing Descriptor Blocks: Configuration and implementation Version Dynamic routing protocol port number or protocol number 7 Routing via 192.168.12.1, Serial0/0 (Note that in the actual environment, the situation may be quite different). VLAN works on the second layer of the OSI reference model Route-map cisco permit 20 match ip address 2 set metric 20 BGP Identifer ROUTER-ID and OSPF selected routerID consistent manner Experimental topology and description 1 NEXT_HOP to 10.1.123.2 , then if C is not on the router to the IP of PVC , will be a problem, so this should be taken into account. Aggregate-address summary address suppress-map xxx as-set These MAC addresses as VLAN bridge spanning tree ID in the MAC address portion. Different switch models support different available MACs Blocking to forwarding state usually takes 30-50s (default 50S , ie 20+15+15 ), this time can also be adjusted by configuring the spanning tree timer. Example 2 of ip community-list (logical relationship): [20/0] via 10.1.12.1, 00:02:57 Maximum route entry 4 If multiple candidate default routes are specified using ip default-network , then the lowest AD will become the default route and set as the default gateway ( gate of last resort ). If AD is equal,ccnp switch 7.0 pdf, then show ip route The first one is displayed as the default gateway. If both ip defaut-network and ip route 0.0.0.0 0.0.0.
