What is configure on CE using EVPN method Multihoming Active Active

[ditoprasetya]

Please send me other reference link documentation on cisco apart from this "https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/mp_l2_vpns/configuration/xe-16-9/mp-l2-vpns-xe-16-9-book/evpn-multihoming.html" because this documentation not explain for configure on CE/Switch.

Thank's

Hi,

CE1 uses a port channel consisting of links, L11 and L12, to connect to PE1 and PE2, respectively.

the port channel can support flow-based load balancing for traffic egress towards PE1 and PE2.

Hope the information helped.

Hi pman,

Thanks for the reply.

when I configure the lacp on the port on the router CE the port turns off. Can I use the "ON" mode?

Because I using version the router CSR on the my eve-ng still running 16.09.07

Hi,

LACP should configure according to the following example (without "on" mode):

side 1: active

side 2: active

OR

side 1: active

side 2: passive

Hi pman,

Actually, I mean I'm not using LACP on the port. is it possible to use the on mode without using the active-active or active-passive LACP method for from CE to PE ?

[pman]

yes, 

If I'm not mistaken it should be something like this:

side1:

interface GigabitEthernet1
channel-group 1 mode on

!There are versions that do not have the word "on" and the following command is sufficient: "channel-group 1"

!

interface Port-channel1
ip address 1.1.1.2 255.255.255.0

side2:

interface GigabitEthernet1
channel-group 1 mode on

!There are versions that do not have the word "on" and the following command is sufficient: "channel-group 1"
!
interface Port-channel1
ip address 1.1.1.1 255.255.255.0

output example:

In the case of EVPN Multihoming I saw the following restrictions:

Restrictions for EVPN Multihoming

• The number of bridge domains that are supported are 16000.

• The number of EFPs or service instances that are supported per physical interface are 8000.

• Stateful Switchover is not supported.

• IP learning is not supported on Cisco ASR 1000 Series Aggregation Services Routers.

• Only all-active redundancy mode (2 or 2+ PEs in the same redundancy group sharing the same ESI and all forwarding traffic) is supported.

• Single-active mode is not supported.

• Only access-side flow-based load balancing with multihoming LAG ON mode is supported. Any ether-channel signaling (LACP or PAgP) is not supported.

• MAC mobility and duplication detection is not supported.

• Per-EVI and per-MAC labeling is not supported. Only per-BD and per-CE labeling is supported.

• Only type 3 ESI is supported as defined in section 5 of RFC7432. Type 3 ESI consists of PE System MAC address and local discriminator.

• Port-channel signaling is not supported.

• The port-channel should be configured in ON mode only.
