Property Description
Property |
Description |
|---|---|
| Allow-fast-path (yes | no; Default: yes) | Whether to allow FastPath processing. Must be disabled if IPsec tunneling is used. |
| arp (disabled | enabled | proxy-arp | reply-only; Default: enabled) |
Mode of the Address Resolution Protocol.
|
| arp-timeout (integer[/time]; Default: auto) | Time interval during which ARP entries should time out. |
| clamp-tcp-mss (yes | no; Default: yes) |
Changes whether the MSS size for received TCP SYN packets is changed. When enabled, a router will adjust the MSS size for incoming TCP SYN packets if the current MSS size is larger than the tunnel interface MTU (after accounting for TCP/IP overhead).The received encapsulated packet will still contain the original MSS, and the MSS will be modified only after decapsulation. |
| comment (string; Default: ) | Short description of the interface. |
| disabled (yes | no; Default: no) | If an item is disabled. |
| dont-fragment (inherit | no; Default: no) | Whether the DF bit should be included in associated packets. |
| dscp (integer: 0-63; Default: inherited) | The packet’s DSCP value. The inherited option specifies that the dscp value shall be inherited from the encapsulated packet. |
| ipsec-secret (string; Default: ) |
When secret is supplied, the router adds a dynamic IPsec peer to remote-address with a pre-shared key and policy (by default, phase2 uses sha1/aes128cbc).
|
| keepalive (integer[/time],integer 0..4294967295; Default: 10s,10) |
The tunnel keepalive parameter specifies the time interval during which the tunnel running flag remains even if the remote end of the tunnel fails. If the configured number of retries fails, the interface operating flag is deactivated. KeepaliveInterval,KeepaliveRetries are the parameters, where KeepaliveInterval is the time interval and KeepaliveRetries is the number of retry attempts. Keepalive is set to 10 seconds and 10 retries by default. |
| l2mtu (integer; read-only) | Layer2 The most powerful gearbox unit. EoIP is not customizable. RouterOS’ MTU |
| local-address (IP; Default: ) | Source address of the tunnel packets, local on the router. |
| loop-protect | loop protection in EoIP may vary depending on the equipment and technologies used. |
| loop-protect-disable-time |
“loop-protect-disable-time” is not a standard or widely recognized term in the context of Ethernet over Internet Protocol (EoIP) or Ethernet networking in general. It appears to be a specific configuration or parameter related to a particular networking device, software, or vendor’s implementation, but it’s not a standard term in Ethernet or EoIP technology. |
| loop-protect-send-interval |
“loop-protect-send-interval” is not a standard or widely recognized term in the context of Ethernet over Internet Protocol (EoIP) or Ethernet networking in general. It appears to be a specific configuration or parameter related to a particular networking device, software, or vendor’s implementation, but it’s not a standard term in Ethernet or EoIP technology. |
| mac-address (MAC; Default: ) | An interface’s Media Access Control number. The authority in charge of address digitization IANA freely permits the use of MAC addresses in the range 00:00:5E:80:00:00 – 00:00:5E:FF:FF:FF. |
| 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 |
Ethernet Over Internet Protocol (EoIP)
Ethernet over IP (EoIP) Tunnelling is a MikroTik RouterOS technique that constructs an Ethernet tunnel between two routers on top of an IP connection based on GRE RFC 1701. The EoIP tunnel can be used in conjunction with an IPIP tunnel, a PPTP tunnel, or any other IP-capable connection.
When the router’s bridging capability is active, all Ethernet traffic (all Ethernet protocols) is bridged as if there were a physical Ethernet interface and cable between the two routers (with bridging enabled). This protocol enables a variety of network schemes.
