? 10.1.12.1 from 10.1.12.1 (1.1.1.1) 5.5.5.5 status Routing table You can use loop guard to prevent alternate or root ports from becoming designated ports because of a failure that leads to a unidirectional link. This feature is most effective when it is enabled on the entire switched network. Loop guard prevents alternate and root ports from becoming Designated ports, and spanning tree does not send BPDUs on root or alternate ports. If the route learns to an EBGP neighbor, it is reflected to all client and non- client IBGP neighbors. 10.1.23.2 An escape character that is used to convert the control character immediately following it to a normal character Then let's go to R4 and see: Generally seen between switches or between switches and routers and servers 30.30.30.0/24 For different routing protocols, the corresponding AD values ​​are shown in the table below. This is a well-known convention: The switch configured with Uplinkfast needs to be a stub switch or an access layer switch in the network three-layer structure. It cannot be the root bridge. Scp: Database agent URL Routing entry for 100.100.100.0/24 Static route associated with the outbound interface Redistribution between different OSPF processes Ip arp inspection vlan 100 logging acl-match none Set ip next-hop recursive This property may not be supported, but even if it is not supported, the route containing the property should be accepted and passed Access-list 1 permit 1.1.1.0 0.0.0.3 route-map test permit 10 Summary 29 100 Ip dhcp snooping Port Relevant points Route Dampening The pVLAN must be configured on a switch in transparent mode. Also requires VTP version 1 or 2 . It is forbidden to configure the Layer 3 VLAN interface as a secondary VLAN . 1 : Request message, requesting all or part of the routing information from the neighbor; None 192.168.1.0 will pass the default route of 0.0.0.0 into RIP , and R2R3 will learn. // There are routes in the routing table of R3 : 1.1.1.0 , 2.2.2.0 , 192.168.12.0 About IP Routing Preferably , the routes sent by the EBGP neighbors (relative to the IBGP neighbors) are preferred to the EBGP routes in the EBGP and IBGP . Note that the first six rules in the BGP routing rules cannot be determined. Only in case of circumstances. IBGP is synchronized with IGP R3-R4 ; R4-R5 ; R3-R5 maintains IBGP neighbor relationships and uses their respective LOOPBACK ports as update sources and establishes Bgp cluster-id 222.222.222.222 protocol description Neighbor maximum-prefix xx Solution: The way to redistribute static summary route to avoid the sub-optimal routing and other issues UDLD mode of operation Neighbor 1.1.1.1 remote-as 123 As OSPF2 create a route in the static summary routes ( the Null0 ), and static routes redistributed into OSPF1 modified OSPF1 administrative distance, the OSPF1 priority than OSPF2 administrative distance Redistribute connected route-map test None Match ip address prefix-list 1 router bgp 1 Local origin Receiving behavior Unicast update 2/1 BGP path/bestpath attribute entries using 248 bytes of memory 0 BGP route-map cache entries using 0 bytes of memory ( Routing Table ) , the routing table is loaded with routing entries ( routes ) learned by the router . The routing entries are composed of routing prefixes (destinations associated with routes), routing information sources, outgoing interfaces, or next hop IPs . The router obtains routing entries and maintains its own routing table in a static or dynamic manner. Native vlan Next Hop 0 ,ccnp route 2018, 1 , x in the matching table ( x does not matter) FastEthernet0/0 - Group 1 State is Active Windows system), at the same time reply a Gratuitous ARP response to inform the peer that there is a duplicate IP address. 4. Proposal/Agreement Sequence Port Next Hop s> 172.16.2.0/24 Show ip b rib-failure * i distribute-list ^$ 200 i ? / / used to match summary routes This is a very typical scenario. GS_SW is an aggregation layer switch that runs OSPF with the core switch . The GS_SW needs to advertise the network segment corresponding to the VLAN to be hanged , so that the core switch can learn the relevant routes. Then, once GS_SW announces the network segment corresponding to these VLANs in the OSPF process , the corresponding SVI interface will flood the OSPF HELLO message to the VLAN , and these messages are actually redundant.
