Use ip community-list to match the community value Let's take a look at the role of these well-known values ​​of community : Switchport access vlan 10 interface fast0/24 This is the ICMP redirect message sent by R1 to R3 . Note that the Gateway address field in the header is filled with the next hop IP that is closer to the destination than the destination . R3 In this step, we run the BGP protocol on the above basis to complete the establishment of basic BGP neighbor relationships: Priority , which is 3 bits long, indicates the priority of the frame. The value ranges from 0 to 7. The larger the value, the higher the priority. 10.1.13.1 Migrate to the Established state if you receive a keepalive message from the other party Route-map test permit 10 ? Y 10.1.23.2 from 10.1.23.2 (10.1.23.2) STP (PVST) Router(config-dhcp)#network [network address][subnet mask] Port What is an invalid arp entry: Field Set comm-list del delete route-map test permit 20 Router bgp 123 Protocol overview Router ospf 1 Network 100.0.2.0 mask 255.255.255.0 SW2 is the core layer switch, deploying DHCP relay Distribute-list 62 Network 192.168.23.2 0.0.0.0 area 0 distribute-list route-map test in If the routes are from EBGP neighbors, it is preferred that the oldest EBGP neighbor came routing, reduce the impact of the roll (this provision mainly EBGP 3.3.3.3 Route reflector planning principle In AS inside, due to the presence IBGP split horizon,ccnp route practice questions, making BGProuter had twenty-two established between IBGP connection, in order to get the full BGP routing updates, but this is a very low scalability approach, but also brought to the network device The two effective ways to solve the IBGP scalability problem are route reflectors and federation. Compared with the federation, the route reflector has the advantage that all routers in the federation need to support and understand the federated mechanism. The route reflector only needs the RR to understand the reflector mechanism. In addition, the implementation mechanism of the route reflector is relatively simple. Of course, if you want to manage large-scale AS with various EBGP mechanisms , then the federation will be a better solution.
