Static route redistribution enters the ospf deep learning router and layer-3 Switch have formed an ospf neighbor relationship. Now we need to connect the remote site router (Outer Port: 218.61.194.99) connected to the ipsec vpn of this router) the CIDR Block (172.17.99.0/24) under is declared and re-distributed to ospf, so that the layer-3 switch can dynamically learn the route entry www.2cto.com of the remote site. The local router configuration is as follows: interface GigabitEthernet0/1 description IPSecVPN ip address 255.255.255.255.255.240 [egress gateway address is unknown] duplex auto speed auto crypto map map1 router ospf 100 redistribute static subnets [redistribution of static routes] ip route 0.0.0.0.0 0.0.0.0 61.161.193.177 [default route] ip route 172.17.99.0 255.255.255.0 218.61.194.99 [Note: because there is no route entry 218.61.194.99, ospf cannot resend this static route] ip route 218.61.194.99 route 255.255.255 61.161.193.177 [Add a route entry to 218.61.194.99, enable the last static router configured to work] Or www.2cto.com ip route 172.17.99.0 255.255.0 61.161.193.177 [direct the 172.17.99.0/24 network segment to the internet gateway egress] the remote router configuration is as follows: interface FastEthernet0/0 description isp ip address too many route 248 ip nat outside ip virtual-reassembly ip route-cache flow duplex auto speed auto crypto map map1 ip route 0.0.0.0 0.0.0.0 218.61.128.97 author Cash
