The red font part of the above output is the layer 2 MAC information and so on. R1 0200 – 03FF The PMTU will become 1300 bytes. Epoch 0 Interface fast1/0 Ipv6 mtu 1400 *>i2001:5555::5/128 Run OSPFv3 as shown Generally, it is 60-240 seconds longer than the invalid timer . If this time also expires, the routing entry is completely deleted. Cisco default 60s (note than invalidtimer multi- 60s ), RFC default 120s 2001:1::1 The command distribute-list out works only on the routes being redistributed by the Autonomous System Boundary Routers (ASBRs) into OSPF. It can be applied to external type 2 and external type 1 routes, but not to intra-area and interarea routes. R1 goes to ping R4 and can ping . Transition from the old routing protocol to the new routing protocol Image Hop-by- hop option header Hop-by-Hop Options Header (Protocol 0 ) Metric: 10 Image Image Run OSPFv3 as shown DHCP PD The ISATAP router thus traverses the entire IPv4 network. Bgp router-id 3.3.3.3 When the GW connects to the outgoing interface of ISP2 and DOWN (that is, ISP2 hangs), then switch to ip next-hop recursive, which is ISP2. BGP4+ , also known as Multiprotocol BGP ,ccna dumps 2019 free download, extends the BGP-4 specification to support new address clusters such as IPv6 , IPX , VPN, and more. Therefore, BGP4+ can carry routing information for IPv6 and other protocols including IPv4 . RFC2858 and RFC2545 defines the BGP4 + process IPv6 attributes updated. Routing entry for 192.168.1.0/24 The linklocal address is only valid within the link range, so you need to specify the local interface to which this linklocal neighbor address is connected . Group-ID This field can be 112 bits long to identify multicast groups, and 112 bits can generate up to 2112 group IDs . :: abcd / 96 (front 96 th 0 , keep the back abcd is the IPv4 address) Y Re-routing release ( Redistributing Routing Protocols ) The fragment reassembly function is performed by the source end itself, and the path MTU is discovered through the PMTU mechanism. Sequence of next hops. The acceptable range is from 1 to 65535.

If it is 0 , the announcer cannot route data.

The IP address of the SVI port of VLAN20 is This RS message sent by the ISATAP host will be routed in the IPv4 network and eventually forwarded to the ISATAP router. This will cause the router to immediately respond with an RA : The simple horizontally separated rule is that the update message sent from an interface does not contain the network contained in the update received from the interface. In other words, the route I received from this interface will not be from this interface. Send it back. UP Flags 4bits , 0000 : permanently assigned or well known ; 0001 : temporary During the transition of the network from the IPv4 single-protocol network to the IPv4-IPv6 IS-IS router, this command maintains the IS-IS adjacency between IS-IS routers using different protocol sets . It prevents IS-IS routers that use different protocol sets from performing hello checks and losing IS-IS adjacencies. After the network switch or transition is complete, you can configure the adjacency-check back.
