Cisco to linux tunnel

思科的隧道默认是gre模式, 用tunnel mode ipip可以选择ipip模式

Cisco配置:

interface Tunnel0
ip address 172.16.1.1 255.255.255.0
ip tcp adjust-mss 1420
tunnel source 10.23.30.1
#tunnel mode  ipip
tunnel destination 10.23.30.206

linux下的操作:

linux下的操作:
modprobe ip_gre
iptunnel add tun0 mode gre remote 10.23.30.1  local 10.23.30.206 ttl 225
ifconfig tun0 172.16.1.2/24
ifconfig tun0 up
ifconfig tun0 pointopoint 172.16.1.1
ifconfig tun0 multicast

tunnel bandwidth

tunnel checksum

tunnel destination

tunnel endpoint service-policy output

tunnel entropy

tunnel key

tunnel mode

tunnel path-mtu-discovery

tunnel rbscp ack_split

tunnel rbscp delay

tunnel rbscp input_drop

tunnel rbscp long_drop
