gre: Generic Routing Encapsulation package support
The package supports Generic Routing Encapsulation support by registering following protocol kinds:
-gre
-gretap
-grev6
-grev6tap
Following options are valid for gre and gretap kinds:
-ipaddr
-peeraddr
-df
-mtu
-ttl
-tunlink
-zone
-ikey
-okey
-icsum
-ocsum
-iseqno
-oseqno
The gretap kind supports additionally the network option
Following options are valid for grev6 and grev6tap kinds:
-ip6addr
-peer6addr
-weakif
-mtu
-ttl
-tunlink
-zone
-ikey
-okey
-icsum
-ocsum
-iseqno
-oseqno
The grev6tap kind supports additionally the network option
Typical network config for a GREv4 tunnel :
config interface 'gre'
option peeraddr '172.16.18.240'
option mtu '1400'
option proto 'gre'
option tunlink 'wan'
option zone 'tunnel'
Typical network config for a GREv4 tap tunnel :
config interface 'gretap'
option peeraddr '195.207.5.79'
option mtu '1400'
option proto 'gretap'
option zone 'tunnel'
option tunlink 'wan'
option network 'wlan_ap'
I added myself as maintainer for the moment; feel free to change.
