實驗32大量分支GREoverIPSec接入的簡易配置(精)

60606060大量分支GREoverIPSec接入的簡易配置、組網(wǎng)需求客戶的網(wǎng)絡(luò)拓撲比較大，一個中心網(wǎng)點和N個分支網(wǎng)點，且每個分支網(wǎng)點都需要利用GREOVERIPSe與中心網(wǎng)點建立VPN連接。由于GRE!道有一定的局限性，Tunnel接口過多，造成配置的復(fù)雜，而Tunnel接口的最大數(shù)目為4096個，那么，分支數(shù)目超過此數(shù)就無法繼續(xù)建立GRE!道，且還沒有算上有些是備份的鏈路。采用P2MP各大大簡化Tunnel接口的配置，且也解決了Tunnel接口數(shù)目不足帶來的問題。同樣，設(shè)備的公網(wǎng)出接口數(shù)目是有限的，我們不可能在 N個出接口上建立IPSec隧道。采用IPsec的模板配置，解決相應(yīng)配置的問題。二、組網(wǎng)拓撲圖實驗所用設(shè)備:中心設(shè)備為SecBlade防火墻插卡；軟件版本Feature3171P11;公網(wǎng)出接口G0/3:172.16.10.1。分部一設(shè)備為SecBlade防火墻插卡；軟件版本Feature3171P11;公網(wǎng)出接口G0/3:172.16.30.1。分部二設(shè)備為SecPathV3防火墻；軟件版本Release1662P07;公網(wǎng)出接口G0/1:172.16.20.1。因特網(wǎng)設(shè)備為S7503E-S交換機；軟件版本Release6616P01;實驗中所用接口為G0/0/25:172.16.10.2，G0/0/27:172.16.30.2，G0/0/28:192.168.20.1 。
