The default is 6 update cycles, which is 180s . The route entry tag when an entry with a larger hop count is received 0.0.0.0 100 i PVLAN considerations Passive-interface defualt Configured MAC Addresses : 0 !! Manually configured secure MAC address, not here MAC sublayer 5.5.5.5 *>i The route closest to BGP NEXT_HOP is preferred , and the route is the route with the smallest IGP metric to the next hop router . Use CDP to detect next-hop IP reachability in PBR environment (without optional parameters) S Router bgp 200 R1(config)# access-list 1 deny 11.11.11.0 R1(config)# access-list 1 permit any R1(config)# route-map rp permit 10 R1(config-route-map) match ip address 1 R1(config )# router bgp 100 Router b 300 Ip arp inspection vlan 100 logging acl-match none B performs the corresponding checksum confirmation according to the type of the connection, and after confirming by these checksums, it is sent to the upper layer. Circuit-ID suboption fields After the TCP session is established, both neighbors must send an OPEN message. Both parties use the OPEN message to identify themselves and specify their own BGP running parameters. If the open message is accepted, a keepalive message is sent back for confirmation, and the update message can be sent after confirmation . The OPEN message contains the following: General BGP routers do not accept containing its own AS routing information number, but can neighbor routing sources neighbors allowas-in a few of my as numbers , to make an exception. Example 2 of ip community-list (logical relationship): Neighbor 4.4.4.4 route-map LP out Interface vlan 10 The DA 40bit multicast address is used to indicate that this FRAME is an ISL . AS number of the AS neighbor Advance It does not modify the original data frames, the processing efficiency than 802.1Q higher VLAN is a very fundamental working mechanism of Layer 2 switches. Interface: Interface for forwarding packets. Corresponding hwidb fast_if_number 4 Corresponding hwidb firstsw->if_number 4 BGP policy accounting on input is enabled. BGP table version is 3,ccnp switch udld, local router ID is 3.3.3.3 In the initial situation, when R2 updates 192.168.12.0/24 route to R3 , we look at the attributes of the route prefix in the updata message: DLY=2560 , because the DLY of the R2 F0/0 interface is 100 microseconds. The unit in the message is 10us , so 10*256=2560 , this value is the value carried in the DLY field in the message . The value of the bandwidth is also similar. This can all be calculated, no problem.
