ccna mock test

Gateway of last resort is 172.16.12.1 to network 192.168.1.0 !! ipv4 routing,ccna mock test, so that the route can access the tunnel destination , which is 10.1.23.3 There is a network environment in which two IPv4 networks are connected by a pure IPv6 provider, and then IPv4 routes have to be exchanged through BGP IPv6 peers. Because BGP4+ supports IPv4 and IPv6 protocol clusters, this is perfectly fine . Ipv6 access-list ipv6only-network permit 2001:1::/64 any Neighbor 2023::2 activate exit-address-family Image DHCPserver configuration RPF nbr: FE80::CE02:1BFF:FE54:0 IPv6 Address(es): FE80::FFFF:FE10:4 System Id Type Interface IP Address State Holdtime Circuit Id Ipv6 nat Contains MTU , prefix information, etc. Image ISATAP is an IPv6 transition mechanism that is very easy to deploy and use . In an IPv4 network, we can do it very easily Segment header Fragment Header (Protocol 44 ) 1/256 Linklocal address, and IPv6 global unicast address. This will be described below. Bytes tag Image Neighbor discovery and adjacency formation mechanisms are the same They will be written in binary form, in fact, we only consider a third 8 bit group can be, because it is the only change 0xF895 technical background description ::FFFF: 4.4.4.4 The IPv6 host on the left wants to communicate with the IPv6 host on the right to issue the original IPv6 packet. As shown in FIG: Metric =0 After the end-to-end IPv6 tunnel is established, IPv6 traffic can communicate. 5 : local site range; Certification There is an address pool on R1 . If R2 wants to use the address pool of R1 ( IPv6 DHCPserver ) to allocate it to users on its intranet, then you can make Image Router(config-if)# ipv6 rip xxx metric-offset ? Multicast address of all groups to which the host belongs Prefix readdressing Image Link LSA ( LSA Type 0x0008 ): Each link has a link LSA . This new type provides the router's link-local address and lists all IPv6 prefixes for the link. 15 R1 Image Image Wherein R2 is as follows: ACL Wherein, R2 back to R1 of ICMPv6 error message is as follows: Router-id 2.2.2.2 The configuration of PE2 is as follows: Route refresh: advertised and received (old & new) Address family IPv6 Unicast: advertised and received ipv6 MPLS Label capability: advertised and received FastEthernet0/0, Forward, 00:00:04/00:03:24 Ipv6 unicast-routing interface fastEthernet 0/0 Difficult analysis These modes generally only be on high-end Cisco device applications , such as 7200 series routers . Or 12,000 Series routers . Command : ip route-cache optimum show ip cache optimum IPv6 prefix The AD value of 11.11.11.0/24 is adjusted to be larger than OSPF , for example 130 . So the configuration is as follows: Ipv6 address 2002:CA65:1703 ::FFFF/64 ipv6 enable Address-family ipv6 neighbor 2001::1 activate What happens to the two-way re-release of RIP to OSPF on R3 ? We assume that the configuration completed on R3 , the route 192.168.1.0 will be injected into OSPF by R3 , and will be updated to R1 , and then updated by R2 to R4 . At this moment, R4 learns this from both OSPF and RIP . Routing, what would it do? Of course, OSPF is preferred because AD is small, so in its routing table, the route about 192.168.1.
