Good day!
I've read a lot of docs, forums and wiki about mikrotik-cisco trunking and link reservation.
Here is my scheme:
1) two Mikrotik routers with two trunk ports to each catalyst switch
2) two access-layer Cisco switches
When each Mikrotik has just one trunk link to the switch, it is quite clear "Mikrotik router on the catalyst stick"
http://wiki.mikrotik.com/wiki/File:Image12005.gif
But what to do, when each catalyst has two trunk links to each mikrotik router?
If we'll have two L3 switches (3750 for example) instead of mikrotik, we'll create
vlan 3
vlan 4
!
int vlan 3
ip ....
int vlan 4
ip ...
!
int g0/1
sw mode trunk
int g0/2
sw mode trunk
and that's all - vlans are travelling through the trunk links and communicate with other vlans with the help of inter-vlan routing.
How to configure the same thing on the Mikrotik?
Let's create the analog of "int vlan 3" on the Mikrotik 2
/interface vlan
add name=VLAN3 vlan-id=3 interface=ether2 disabled=no
/ip address
add address=10.1.1.2/24 interface=VLAN3
from this config we can see, that int VLAN3 belongs to ethernet2 only! but what about ethernet1 for example?
How could the clients from sw1 communicate with mikrotik2 when mikrotik1 fails? (in case of vrrp of course)
How can we make the eth1 and eth2 interfaces full-fledged trunk links?
