ccna course duration

This technology is used less and is one of the first conversion mechanisms of the IETF . The automatic IPv4- compatible tunneling mechanism allows only IPv6 data between two dual-stack hosts to be automatically tunneled (without manual configuration) over the IPv4 network. This mechanism allows for isolated hosts and another on an IPv4 network FastEthernet0/0 Protocol Interface Now let 's do the following configuration on R2 : Ipv nd prefix default ? In the above figure, we inject OSPF routes into RIP . Traditionally, you can only set metrics on all incoming routes . However, with route-map , we can associate a defined one when configuring re-issue commands. A good route-map , in the route-map , we can create different properties or actions for different routes by creating multiple serial number statements. Because IS-IS runs on top of the data link layer,ccna course duration, that is, it runs on top of the link layer protocol and requires CLNP support. Therefore, IPv6 IS-IS cannot be used on a remote IPv6 network connected through a tunnel . Configuring a tunnel is a static IPv6 over IPv4 tunnel. Group-ID This field can be 112 bits long to identify multicast groups, and 112 bits can generate up to 2112 group IDs . Ipv6 ospf 100 area 2 twenty two Ipv6 local pool dhcppool 2001::/64 64 interface Serial0/0 Interface Loopback0 ipv6 enable The configuration of R2 is as follows: Set as-path set community Dual-stack ( Dual Stack ) Area 1 range 2001:1::/32 R2(config-router)# distribute-list 1 in fa0/0 We see that the PC first generates an interface ID of 64 bits according to its locally configured IPv4 address: 1.1.1.1 : Prefixing Prefix announcement Set ip next-hop 10.2.2.2 PC can take the initiative to send RS to trigger router sends RA , without waiting for RA periodically sent before closing time to the RA . BGP Image Network 4.4.4.4 0.0.0.0 area 0 The tunnel is automatically enabled between isolated hosts on the IPv4 network to implement IPv6 data transmission in the tunnel. Source and destination IPv6 addresses are lower 32 ISATAP tunnel ! 1/32 Ipv6 address 2001:23::2/64 Image Interface Serial0/0 ipv6 enable Assume that R1 is the stub node in the network structure. Therefore, on R2 , the extra routes are filtered out, and only the F1 and 0- port routes of R3 are advertised to R1 . We filter out specific routes on R2 : Required IPv6 address R1 , R2 establish IPv6 in IBGP neighbor relationship (based LOOPBACK Interface) Valid lifetime is similar to dhcp in the Lease Time . If the address exceeds the valid lifetime , the node will set this address to inactive and then delete . Between the preferred time and the valid lifetime is called the deprecated state. This state is a buffer . It is probably a deprecated state. When the address reaches this time period, the address cannot be actively initiated. The connection can only be passively accepted. Connection, this is also designed to ensure the upper layer application, but after the valid lifetime time address becomes invalid , then any connection will be down .
