ccnp switch v7 sba

Configure this command. When routing, the router only compares all routing entries with the AS_CONFED_SEQ attribute. This command is used for federated routers, while weight and LP have higher priority than MED. UDP The buddy first introduced the above network environment. This Nima is a fairly classic case. OR1 and OR2 are the egress routers of the network, which are respectively connected to the egress lines of Netcom and telecommunications. PAT is implemented on both egress routers , so that intranet users can access the extranet. In addition to OR1 , There can only be one Isolate vlan in a primary VLAN. Precautions: The difference between set ip next-hop and set ip default next-hop is relatively simple, it is not resolved here. CISCO data forwarding mode 13 *Mar 4 07:02:23.473: DHCPD: relay information option exists, but giaddr is zero. IBGP horizontal segmentation When a route oscillates (continuously fails, recovers), it is assigned a penalty value. The more the swing, the larger the penalty value and the constant accumulation. The "original Ethernet frame" is up to 1518 bytes,ccnp switch v7 sba, the IP MTU of 1500 , plus the source destination MAC address is 12 , the type field is 2 , CRC4 , plus 30 bytes of ISL encapsulation, which is 1548 bytes. OSPF ! Heavy FAQ published 200 i BGP Speaker from IBGP routes learned whether it's advertised to EBGPpeer depends IGP and BGP synchronization to decide IGRP for OSI networks Metric for redistributed routes Mobile routes Configure the switch to verify that the source MAC address in a DHCP packet received on untrusted ports matches the client hardware address in the packet. The default is to verify that the source MAC address matches the client hardware address in the packet. Use set as-path tag to restore, for example, this example on R3 , Diameter refers to a diameter value, the default is 7 . This value is related to the STP timer. If the different diameter values ​​are configured, the switch will automatically adjust the hello and max age timers. This command is usually configured on the root , so that the timer value is passed to other switches through bpdu . Ip dhcp relay information trusted The frame structure formed by the MAC sublayer is mentioned in the introduction above , including IEEE802.3 frames and ETHERNET_II frames. 200 i Access-list 11 deny 192.168.1.0 Interface loopback2 Due to the different port types, the switch processes the frames differently. The following is introduced according to different port types. ... Match ip address prefix-list 1 set metric 200 Switch Virtual Interfaces ( SVI ) no ip dhcp snooping information option Policy-list is only supported in BGP . Other IP routing protocols do not support this feature. BGP stipulates that routes learned through one IBGP are not propagated to all other IBGP neighbors. This is the horizontal split rule of BGP . DAI is an ingress security feature that does not perform egress security checks. 3.3.3.3 External EIGRP Do the following configuration on R2 and test it ( all tested in no ip classless and closed ip cef environment ): 16 bytes R3 and R4 , R4 and R5 establish IBGP neighbor relationships, and R3 R4 R5 uses LOOPBACK as the update source and refers to the neighbor . 100 i 10.1.13.3 The next hop of the route advertised by the device is 0.0.0.0) 200 i Transmit limit accumulator 0x0 (0x0) IP MTU 1500 In AS inside, due to the presence IBGP split horizon, 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.
