Excuse me each great god, and this figure I PC1 and PC2 respectively do the VLAN, demand VLAN10 cannot access to the public, VLAN can access to the public, 20 on the NAT on the router G0/0/0 set the gateway, PC1 and PC2 can access, also made EASY on the router IP, can pass two routers connected directly, but now can't PC2 PING AR2 and PC3, what reason is this excuse me ah!

CodePudding user response:

Pc3 can access AR2, from your description, can explain AR2 pc3 can normal communication, pc1 and pc2 can communicate with each other, can see out to switch to the AR1 or AR1 between AR2 have fault, may be failure 1, 0/0 of the switch/3 port is not through all vlan, possible fault 2: AR1 0/0/0 child port is not correct, divided into some configuration, 3 AR1 to AR2 connectivity may malfunction

CodePudding user response:

See the AR1 and AR2 routing table.. See. Is there a corresponding routing

CodePudding user response:

CodePudding user response:

CodePudding user response:

Estimation is set up routing problem, and visit pc2 pc3, not only to configure ar1, ar2 also should make corresponding configuration

CodePudding user response:

Of a default route on AR1 8 0 to 200.1.1.2 yao should be able to ping AR2 PC2 can't pingPC3 was normal PC2 and PC3 mutual need VPN knowledge
