6.5 Configuring GRE Tunnel
GRE (Generic Routing Encapsulation) specifies a protocol for encapsulation of an
arbitrary protocol over another arbitrary network layer protocol.
GRE defined in RFC 2784 and updated by RFC 2890.
To create a GRE tunnel interface and enter interface configuration mode on JadeOS,
use the following command:
interface tunnel <id>
tunnel mode gre
Figure 6-3 GRE tunnel
To create a GRE tunnel on JadeOS, use the following steps:
(JadeOS)(config) #interface tunnel 1
(JadeOS)(config-if) #tunnel mode gre
(JadeOS)(config-if) #ip address x.x.x.x/x
(JadeOS)(config-if) #tunnel source x.x.x.x
(JadeOS)(config-if) #tunnel destination x.x.x.x
(JadeOS)(config-if) #tunnel key <0-4294967295>
(JadeOS)(config-if) #tunnel checksum
6.6 Configuring DHCP
The Dynamic Host Configuration Protocol (DHCP) is a network configuration proto-
col for hosts on Internet Protocol (IP) networks. UDP protocol mainly has two usages:
- Reduce client’s configuration burden, used in the change of office.
- Reduce network administrator’s configuration burden. UDP achieves address
unified distribution, centralized management and DHCP Snooping rational
using, which is good for avoiding network attack and ensuring resource ra-
tionally in use.
Because of the terminal mobility, wireless network architecture has a high standard on
