4-qadam. VPN tunnel ishini tekshirish
Tunneling ishchanligini ping utilitasi orqali tekshiramiz. Masalan, bosh ofisdan:

R-MAIN#ping 10.0.0.2 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 10.0.0.2, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 16/17/20 ms

sh cry ips sa peer 2.2.2.2 buyrug’I bilan paketlarning himoyalangan tunnel orqali o’tayotganligiga ishonch hosil qilamiz.

R-MAIN#sh cry ips sa peer 2.2.2.2 interface: Tunnel1 Crypto map tag: Tunnel1-head-0, local addr 2.2.2.2 protected vrf: (none) local ident (addr/mask/prot/port): (0.0.0.0/0.0.0.0/0/0) remote ident (addr/mask/prot/port): (0.0.0.0/0.0.0.0/0/0) current_peer 2.2.2.2 port 500 PERMIT, flags={origin_is_acl,} #pkts encaps:5, #pkts encrypt: 5, #pkts digest: 5 #pkts decaps: 5, #pkts decrypt: 5, #pkts verify: 5

Oxirgi ikki satr shuni ko’rsatadiki, marshrutizator 5 ta xabarni shifrladi va yubordi va shuncha qabul qilib deshifrladi. Qandaydir paket bizning marshrutizatorlarimiz tunneli orqali o’tsa bu hisoblagichlar har safar ishlaydi.
5-qadam. Marshrutlash
Har ikkala ofis bir biriga ulana olishi uchun har bir qurilmaga mos marshrutlash satrlarini qo’yish talab etiladi.
