FastEthernet1/0 Metric value: The overhead of the router to reach the destination is an integer between 0 and 15 . Image PE1# show bgp all neighbors 4.4.4.4 Image --- PMTUD 300 Ipv6 nd prefix 2001:0001::/64 Address-family ipv6 Manually modify the hop count of RIP . First configure matching routes Bgp router-id 3.3.3.3 Image If R2 on ip route 1.1.1.0 255.255.255.0 null0 , this time there is no routing table OSPF of 1.1.1.0 routing the unsuccessful thus re-release, so R3 can not learn the 1.1.1.0/24 route; ? Ip cef The router uses this information to construct a new Layer 2 header for the data frame and then forwards the message to the outbound interface pointing to the next hop. Traffic share 1 A000 – BFFF This is the problem, how to solve it? Very simple, on the OR2 , deploy PBR , as long as the server data from Netcom, all forced to OR1 , it is solved. FIG above, R1 to R2 update 1.1.1.0 , . 1 hop, when R1 DOWN off, and R3 to R2 update 1.1.1.0 is . 5 hopping, R2 up to R1 route will vary with invalid timer expires becomes pdown State, then enter the timer of the holddown timer The configuration of P is as follows: Ipv6 enable Interface When OSPF to IBGP when routes are heavy, because the OSPF of AD than IBGP of AD should be small, so there is no problem of sub-optimal routing path or loop: Tunnel0 [up/up] R3.00-00 Multi-protocol BGP overview Mpls label range 200 299 mpls ldp router-id loopback0 Image !! This must be knocked Router isis 200::/7 is reserved for the network service access point NSAP . Currently, the NSAP reserved space is not used . The NSAP address is mainly used in the ATM technology. Test description: ping FF04::1 on R2 and Fa1/0 on the outbound interface Metric problem Respond to an RA after the router receives the RS : Index 1/1/1, retransmission queue length 0, number of retransmission 0 First 0x0(0)/0x0(0)/0x0(0) Next 0x0(0)/0x0(0)/0x0(0) OSPF routes take effect, and only 1.1.1.0 routes survive. The source of continuous routing is direct routing, or RIP . Ipv6 address 2002:CA65:1703 ::FFFF/64 ipv6 enable Image Image The source address of the RA packet, whether it is a linklocal address Difficult analysis Ip route 100.0.0.0 255.0.0.0 null0 When a node starts the IPv6 protocol stack, each interface of the node automatically configures a link-local address. This mechanism allows two IPv6 nodes connected to the same link to communicate without any configuration. The default gateway recommends using a link-local address because this address is the most stable. Tunnel agent 8 bits FE80:: 5EFE:202:202 2001:1111:: 5EFE:202:202 Ipv6 address 2001:12::1/64 Image ! The next hop of 1.1.1.0/24 , because the AD value of OSPF is better than RIP . Network 192.168.254.0 0.0.0.255 area 1 Prefix announcement When the router performs a classless route lookup (by default, ip classless ), it does not pay attention to the class of the destination address. It performs the longest match between the destination address and all known routes bit by bit . Announce IPv6 prefix on CISCO IOS router Image PE1#show bgp vpnv6 unicast all 2001:5555::5/128 ! When the router is adjacent to the host, they learn in some way. PC configuration Vlan 20 interface fast0/1 Situation 3 Identify the type of message: Set interface Switchport access vlan 20 interface vlan 10 The same prefix is ​​obtained through different protocols, first than AD , and later than metric Use a static route to the next hop The identifier of the authentication item indicates that the entire routing packet needs to be verified. The new routing table is typically sent to neighboring routers on a regular basis, and the triggered update is sent immediately in response to changes in the routing table. Experimental example: Calling in the distribution list Must be zero Vlan 20 interface fast0/1 Between routers, routing information is passed, and the distribution list has absolute control over routing information. Therefore, if it is in the direction, by deploying the distribution list, the specific route can be filtered, so that the local routing routing table of the distribution list is changed, and when the local router updates the routing information to the downstream router,dumps for 200-125, the actually updated content is An entry that is affected by the distribution list.
