I'm trying to learn and understand how to configure and manage an SPB network. I understand that some models are not capable of single-pass inline routing, and I want to make sure I understand the difference in configuration style for both scenarios.
Unfortunately, I currently have no access to models that are SPB capable, so I'm asking here if this configuration is correct or if I missed something. This is purely a learning exercise as I never dealt with SPB before.
This is the topology:
https://ibb.co/wzZFDSg
Assumptions:
Layer2 service.
Same customer on both 1/1/1 ports and 2 vlans need to pass through the SPB domain (I.E voice and data or whatever).
Routing between vlans happens on the customer router connected to BEB1 (not shown in the picture).
This is my configuration:
Code: Select all
# on all BEB and BCB switches:
spb bvlan 4000 ect-id 1
spb bvlan 4001 ect-id 2
spb bvlan 4002 ect-id 3
spb isis control-bvlan 4000
spb isis interface port 1/1/23
spb isis interface port 1/1/24
spb isis admin-state enable
Code: Select all
# on BEB1 and BEB2:
service access port 1/1/1
service 10010 spb isid 10010 bvlan 4001 # do I need admin-state enable here?
service 10010 sap port 1/1/1:10 # do I need admin-state enable here?
service 10020 spb isid 10020 bvlan 4002
service 10020 sap port 1/1/1:20
- Do I need admin-state enable where noted above? As in, everytime I create a service? Or is it there by default?
- This topology has 2 equal cost paths. Do I need bvlan 4001 and 4002, or can I use 4000 (the control-bvlan) for one of those paths?
What's best practice here for this example?
Now for management:
I keep seeing different variations of ALE documentation on this, but assuming everything is correct so far, this is how I believe I can manage this topology for both scenarios of when I have (and don't have) single-pass inline routing devices.
Is this config correct for when all my nodes support single-pass inline routing?
Code: Select all
ip interface BEB1 address 10.0.0.1/24 vlan 4000 # for BEB1
service 14000 spb isid 14000 bvlan 4000
service 14000 sap port 1/1/1:4000
Code: Select all
ip interface BCB1 address 10.0.0.2/24 vlan 4000 # for BCB1
Code: Select all
ip interface BCB2 address 10.0.0.3/24 vlan 4000 # for BCB2
Code: Select all
ip interface BEB2 address 10.0.0.4/24 vlan 4000 # for BEB2
And giving it a default gateway ip static-route 0.0.0.0/0 gateway 10.0.0.254 for remote access?
And like-wise, in case I have older models that do not support single-pass inline routing, then would this config be correct:
Code: Select all
vrf create MANAGEMENT # for BEB1
ip interface MANAGEMENT address 10.0.0.1/24 vlan 4000
ip service all admin-state enable
service 14000 spb isid 14000 bvlan 4000
service 14000 sap port 1/1/1:4000
Code: Select all
vrf create MANAGEMENT # for BCB1
ip interface MANAGEMENT address 10.0.0.2/24 vlan 4000
ip service all admin-state enable
Code: Select all
vrf create MANAGEMENT # for BCB2
ip interface MANAGEMENT address 10.0.0.3/24 vlan 4000
ip service all admin-state enable
Code: Select all
vrf create MANAGEMENT # for BEB2
ip interface MANAGEMENT address 10.0.0.4/24 vlan 4000
ip service all admin-state enable
I guess I could also tag vlan 4000 on a different port (say 1/1/2) and uplink it to the customer's switch, but would it work instead?
Can someone more experienced and involved with SPB share the best way to manage this SPB network for both scenarios?
