Tag 9, type extern 2, forward metric 64 Select the port for the Channel None Port-Security is turned off by default Experimental verification 192.1.168.1 3 0003.47d8.c91f 2BB6488E interface-id 21ae5fbb Use strategy in R3 The experiment is completed here, we set MARK , then we will analyze the impact of various attributes on the routing. 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). It is used to preferentially send packets with high priority when the switch is blocked. For Dot1Q MTU = 1522 The AS_SEQUENCE attribute will be passed to R7 along with the route 11.11.11.0 , so the packet is captured on R7 . The attribute of AS_CONFED_SEQENCE is not visible in the route of 11.11.11.0 , so the external AS treats the federation as a single AS (outside I don't know the situation inside the federation) Router ospf 100 Switchport mode private-vlan host CASE2 : The Native VLAN must match at both ends of the trunk . Otherwise, VLAN traffic will appear. Again rule 11 , it seems to take effect, but this time the R3 of BGP routerID than reform R4 large, found R5 Still preferably R4 ,ccnp route test prep, because "If a path contains RR properties, producer ID to select the optimal path during Instead of RID ” Associate route-map when route is republished (typical case) Redistribute local direct connection network segment into BGP , MED value is 0 ; redistribute local static route into BGP , MED value is 0 The behavior of the router is hop-by-hop. Each router along the path to the destination network must have a route to the destination. Next Hop Switchport access vlan 10 1-9, 11-4094 Redistribute ospf 1 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 . Redistribute ospf 3 subnets route-map OSPF3to2 Is 2 , 3 with AS the first comparison, 2 is MED small it is preferable; 2 with a further comparison, one of external routes it is preferably ( MED not compare) None The configuration of SW2 is as follows: Access-list 1 permit 192.168.1.0 0.0.0.255 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; 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 . FastEthernet FastEthernet IEEE 802.3 The so-called one-arm routing is on the Ethernet port of the router (must be above 100M interface) to carry VLAN traffic, let the router and switch run a trunk , use dot1Q encapsulation, at this time, in order to let the router's Ethernet port support Dot1Q To identify and carry VLAN traffic, you need to divide the subinterface of the physical interface, as shown in the figure above. DHCPsnooping If you want to turn off ICMP redirects, you need to use no ip redirects on the interface . Show ip bgp Interface loopback1 *> 100.0.1.0/24 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, 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.
