EoIP Basic Configuration - using 24hr version [SOLVED]

RouterOS Beginner Basics

Hi all,

I need some tips on basic EoIP configuration. I have a network set up using VMWare looking like the following:

PC1–>Cisco SW1–>Mikrotik1–>Mikrotik2–>Cisco SW2–>PC2

I have managed to get end-to-end connectivity using different subnets at each site but when I try to have the same subnet at each site and use an EoIP tunnel I can’t seem to get it to work (i.e. ping from one side to the other). I’ve looked at various documents but still no cigar. I found one that talked about setting up an encrypted pptp tunnel but interface pptp doesn’t appear to be supported in my version and I installed all packages at installation time :frowning:

PC1 = 192.168.1.2/24 G/W=192.168.1.1/24
Cisco SW1 = Access port VLAN 1 to PC1 and dot1q trunk to Mikrotik1
Mikrotik1 = ether1_to_Cisco_SW1 on 192.168.1.1/24 and ether2_to_Mikrotik2 on 192.168.254.1/24
Mikrotik2 = ether1_to_Mikrotik1 on 192.168.254.2/24 and ether1_to_Cisco_SW2 on 192.168.1.254/24
Cisco SW2 = Access port VLAN 1 to PC2 and dot1q trunk to Mikrotik2
PC1 = 192.168.1.3/24 G/W=192.168.1.254/24

As I understand it you create an EoIP interface, a bridge interface, and add the EoIP and LAN-facing interfaces to the bridge.

For example I have got on Mikrotik1:

interface eoip add name=eoiptunnel remote-address=192.168.254.2 tunnel-id=101 disabled=no
interface bridge add name=bridge1
interface bridge port add bridge=bridge1 interface=eoiptunnel
interface bridge port add bridge=bridge1 interface=ether1_to_Cisco_SW1

And on Mikrotik2:

interface eoip add name=eoiptunnel remote-address=192.168.254.1 tunnel-id=101 disabled=no
interface bridge add name=bridge1
interface bridge port add bridge=bridge1 interface=eoiptunnel
interface bridge port add bridge=bridge1 interface=ether2_to_Cisco_SW2

Can anybody see what I’m missing here apart from my marbles as I’m starting to lose them now, lol. BTW, I’ve just checked the MAC addresses at both ends and they are different.

Regards,

Chris

Put my daughter to bed this evening and thought I would try to get this sorted, and by jove I did. The problem I had was that I was emulating a host using VPCS (this runs alongside GNS3) and for some reason the two VPCS instances at either end of the virtual network would not talk to each other. I have now proved the EoIP tunnel works by adding an IP address in the 192.168.1.0/24 range to the VLAN 1 interface on each Cisco switch and it works! Still don’t know why PPTP isn’t supported in the 24hr version though…

glad you solved it, but everything should be working in the 24h version :-/

Hi,

It seems that when I went to install everything not everything installed. I’ve reinstalled a select few of the packages and got everything working now.
