Port-Security deployment considerations Router(config-router)# distance AD ip-src wildmask acls Switch(config)# interface vlan 255 Full-duplex MAC : The physical layer operating mode provides access when full-duplex. The ETHERNET_SNAP frame can be used to transport multiple protocols. Therefore, SNAP can be seen as an extension that allows vendors to create their own Ethernet transport protocols. Redistribute static subnets Paths: (2 available, best #2, table Default-IP-Routing-Table) Not advertised to any peer Weight The network segment of the network local direct interface enters BGP , the MED value is 0 ; the network local static route enters BGP , and the MED value is 0. If the ibgp keyword is not associated , only EBGP routes will be equivalently load balanced (by default only for EBGP routes). If maximum-paths is not configured , the next routing principle will be followed. As Primary the AS , 201 of Secondary the AS , R2 can be maintained in the original R1 of BGP case of updating the routing and connection is not affected, BGP routing rules 1 Mechanism overview 5.5.5.5 Both SW1 and SW2 can learn, and three-year-olds can do it. R2 //Get out a summary route instead of the default route 1 : RIP-1 ; Scanning messages on the intranet. The destination addresses of these packets are some unknown addresses that start with 192.168 , or even addresses that do not exist at all. The packet is sent to the gateway,ccnp route questions pdf, which is the Layer 3 switch. Since the Layer 3 switch is configured with the default route, these packet destinations are matched by the default route and directed to the egress router, and the summary route is deployed on the egress router. Although the destination address of the packet does not exist in the internal network, it is an IP in the summary route , so it is forwarded back to the Layer 3 switch by the egress router. Then the Layer 3 switch forwards the packet according to the default route. Back to the router, this forms a loop of data.
