what is ccna certification

Tunnel interfaces do not necessarily need ipv6 address , of course, can also be configured v6 address, it does not affect traffic through the router configuration is complete, PC1 can ping through PC2 , Ethereal as follows: Garbage colletion/flush timer 25 Tiao E : global scope; Ip address 4.4.4.4 255.255.255.255 0x7768 Neighbor 2001::1 activate OSPF V2 has similarities with V3 : Wherein R3 is as follows: All options are longer than or equal to 0 Image Then, first R2's own routing table will change, 3.0 routing is filtered out, and R3 is the downstream RIP router, 3.0 can not learn. 00 Ip address 4.4.4.4 255.255.255.255 Protocol Interface Mpls ip Image FastEthernet FastEthernet IEEE 802.3 R1 When ISP1 is down, and the GW does not detect it (that is , the interface of GW connected to ISP1 is not DOWN ), the traffic of PC access 100 is still thrown to ISP1 , which is disconnected.

Note that it is configured in interface mode to set the metric accumulation amount. Optional value 1-16 Configuration example R2 will "translate" the two OSPF routes 3.0/24 and 4.0/24 into RIP and pass it to R1 . R1 will also be able to learn 3.0 and 4.0 routes. Note that the re-released execution location is performed on R2 , that is, at the demarcation point of the routing domain. In addition, the route re-distribution is directional. For example, after we have performed the relevant action, R3 still has no R1 route. Need to further re-publish the RIP route on R2 .
