The EoIP protocol encapsulates Ethernet frames in GRE (IP protocol number 47) packets (just like PPTP) and sends them to the remote side of the EoIP tunnel.
Property Description
Property | Description |
---|---|
arp (disabled | enabled | proxy-arp | reply-only; Default: enabled) | Address Resolution Protocol mode.
|
clamp-tcp-mss (yes | no; Default: yes) | Controls whether to change MSS size for received TCP SYN packets. When enabled, a router will change the MSS size for received TCP SYN packets if the current MSS size exceeds the tunnel interface MTU (taking into account the TCP/IP overhead).The received encapsulated packet will still contain the original MSS, and only after decapsulation the MSS is changed. |
dont-fragment (inherit | no; Default: no) | |
dscp (integer: 0-63; Default: inherited) | DSCP value of packet. Inherited option means that dscp value will be inherited from packet which is going to be encapsulated. |
ipsec-secret (string; Default: ) | When secret is specified, router adds dynamic ipsec peer to remote-address with pre-shared key and policy with default values (by default phase2 uses sha1/aes128cbc). |
keepalive (integer[/time],integer 0..4294967295; Default: 10s,10) | Tunnel keepalive parameter sets the time interval in which the tunnel running flag will remain even if the remote end of tunnel goes down. If configured time,retries fail, interface running flag is removed. Parameters are written in following format: KeepaliveInterval,KeepaliveRetries where KeepaliveInterval is time interval and KeepaliveRetries - number of retry attempts. By default keepalive is set to 10 seconds and 10 retries. |
l2mtu (integer; read-only) | Layer2 Maximum transmission unit. Not configurable for EoIP. MTU in RouterOS |
local-address (IP; Default: ) | Source address of the tunnel packets, local on the router. |
mac-address (MAC; Default: ) | Media Access Control number of an interface. The address numeration authority IANA allows the use of MAC addresses in the range from 00:00:5E:80:00:00 - 00:00:5E:FF:FF:FF freely |
mtu (integer; Default: auto) | Layer3 Maximum transmission unit |
name (string; Default: ) | Interface name |
remote-address (IP; Default: ) | IP address of remote end of EoIP tunnel |
tunnel-id (integer: 65536; Default: ) | Unique tunnel identifier, which must match other side of the tunnel |
Configuration Examples
Parameter tunnel-id is a method of identifying a tunnel. It must be unique for each EoIP tunnel.
