Cisco Router to Mikrotik Router Etherchannel(Bonding) issue

Mon Jul 27, 2020 12:57 pm

Hi All,

I am having issue with configuring Etherchannel(Bonding) between Cisco ASR 920 & Mikrotik CCR1036 router.

CIsco Router Config
----------------------------------------------------------------
interface GigabitEthernet0/0/8
no ip address
media-type sfp
negotiation auto
channel-group 1 mode active
end

interface GigabitEthernet0/0/9
no ip address
media-type sfp
negotiation auto
channel-group 1 mode active
end

ASR-920#show running-config interface po1

interface Port-channel1
ip address 10.189.189.1 255.255.255.252
negotiation auto
end

ASR-920#show etherchannel summary

Group Port-channel Protocol Ports
------+-------------+-----------+-----------------------------------------------
1 Po1(RD) LACP Gi0/0/8(susp) Gi0/0/9(susp)
10 Po10(RU) LACP Gi0/0/5(bndl) Gi0/0/6(bndl)

ASR-920#show ip interface brief
Interface IP-Address OK? Method Status Protocol
GigabitEthernet0/0/8 unassigned YES NVRAM up up
GigabitEthernet0/0/9 unassigned YES manual up up

Port-channel1 10.189.189.1 YES manual down down <----------------------------- Cisco to Mikrotik LACP show down
Port-channel10 103.25.155.129 YES manual up up <----------------------------- Cisco to Cisco LACP show up

** Cisco to Mikrotik LACP link (Port-channel 1) is showing down.
Please help me to get this up and running..
Any help would be appreciated.
Thank You.

Hmm...
I don't see any obvious misconfiguration in your setup.
Just double-checked it with a bonding I have up and running here and the only differences I see is explicit LACP protocol assignment to the interfaces on the cisco side and plain layer2-hashing on the Tik side.

Here's my working config (Tik to catalyst 9300, but it should be universal since it's all iOS):

MikroTik config:
/interface bonding
add arp=enabled arp-interval=100ms arp-ip-targets="" arp-timeout=auto disabled=no down-delay=0ms !forced-mac-address lacp-rate=30secs link-monitoring=mii mii-interval=100ms min-links=0 mode=802.3ad mtu=1500 name=bond0 primary=none slaves=ether9-office1/0/13,ether10-office2/0/13,ether11-office3/0/13 transmit-hash-policy=layer-2 up-delay=0ms

Cisco config:
interface Port-channel10
 description to edge-01
 switchport trunk allowed vlan 1,30,31,666
 switchport mode trunk
 switchport nonegotiate
 hold-queue 1000 out
end

!
interface TwoGigabitEthernet3/0/13
 description to edge-01
 switchport trunk allowed vlan 1,30,31,666
 switchport mode trunk
 switchport nonegotiate
 power inline never
 channel-protocol lacp
 channel-group 10 mode active
 spanning-tree guard root
 hold-queue 1000 out
end

!
interface TwoGigabitEthernet2/0/13
 description to edge-01
 switchport trunk allowed vlan 1,30,31,666
 switchport mode trunk
 switchport nonegotiate
 power inline never
 channel-protocol lacp
 channel-group 10 mode active
 spanning-tree guard root
 hold-queue 1000 out
end

!
interface TwoGigabitEthernet1/0/13
 description to edge-01
 switchport trunk allowed vlan 1,30,31,666
 switchport mode trunk
 switchport nonegotiate
 power inline never
 channel-protocol lacp
 channel-group 10 mode active
 spanning-tree guard root
 hold-queue 1000 out
end

MikroTik is using the slow LACP PDU rate of 30s, what rate is the Cisco LACP channel using? If it's set for 1s, i'd reconfigure to 30 and retest.

Solution:
https://www.cisco.com/c/en/us/support/d ... onfig.html

When you configure port channels with EVC on the ASR 900, you must configure 1 EVC with untagged encapsulation and L2 protocol. For example:

interface Port-channel1
!
service instance 1 ethernet
encapsulation untagged
bridge-domain 1
l2protocol peer
!
