建設(shè)部舉報(bào)網(wǎng)站西安網(wǎng)站建設(shè)方案優(yōu)化
組網(wǎng)需求
如圖1，兩個(gè)IPv6網(wǎng)絡(luò)分別通過SwitchA和SwitchC與IPv4公網(wǎng)中的SwitchB連接，客戶希望兩個(gè)IPv6網(wǎng)絡(luò)中的PC1和PC2實(shí)現(xiàn)互通。
其中PC1和PC2上分別指定SwitchA和SwitchC為自己的缺省網(wǎng)關(guān)。
圖1 配置IPv6 over IPv4 GRE隧道組網(wǎng)圖
配置思路
要實(shí)現(xiàn)IPv6協(xié)議中的PC1和PC2通過IPv4公網(wǎng)互通。需要在SwitchA和SwitchC之間建立直連鏈路，部署GRE隧道，通過靜態(tài)路由指定到達(dá)對端的報(bào)文通過Tunnel接口轉(zhuǎn)發(fā)，PC1和PC2就可以互相通信了。
配置GRE隧道實(shí)現(xiàn)IPv6協(xié)議互通的思路如下：
-
配置物理接口的IP地址，并配置IPv4靜態(tài)路由，實(shí)現(xiàn)設(shè)備可以通過IPv4網(wǎng)絡(luò)通信。
