2 M E1 MPPP bundle to increase the bandwidth SLB Qos instance

No nonsense mppp is a link bundle, which binds two small bandwidths into a logically large bandwidth link.

Of course, the carrier now also provides the E1 multiplexing, which can be bound directly on it.

The client has two 2 M E1 links, which use different carrier circuits, and can be used for Load Balancing through mppp bundling. In the case of circuit failure, the client can be used as a backup link for each other.

The two-end configuration is similar, so only the config

Router

Create mppp interface and mppp group

Interface Multilink1
Description Multilink1 to HQ Multilink1
Bandwidx 3968
Ip address 10.254.250.6 255.255.255.252
Ppp multilink
Ppp multilink group 1

 

Configure two leased lines respectively

After completion, it will be accompanied

No auto-summary
No Kerberos log-neighbor-changes

Test the mppp command show ppp multilink

Basically, the configuration is very simple.

 

There are also voice and viedo conference applications on the client, so some qos settings need to be made at last.

Define access control list matching

Access-list 121 remark VoIP IP address
Access-list 121 permit ip host 192.168.209.250 any
Access-list 122 remark vc ip address
Access-list 122 permit ip host 10.216.242.1 any
Access-list 122 permit ip host 10.216.242.2 any

Define a policy route and set different priorities for different businesses

Match voip streams

Route-map TOS-Mark permit 10
Matches ip address 121
Set ip precedence critical

Match the video meeting stream!
Route-map TOS-Mark permit 20
Matches ip address 122
Set ip precedence flash-override

Default settings
Route-map TOS-Mark permit 30
Set ip precedence routine

Define Qos map & Policy

Class-map match-all VC
Match access-group name TOS-4
Class-map match-all VoIP
Match access-group name TOS-5
!
!
Policy-map QoS
Class VoIP
Priority288
Class VC
Priority640
Class-default
Fair-queue

Matched to interface

Interface Multilink1

Service-policy output QoS

Apply Policy Routing on internal interfaces to prioritize voip/video packets

Interface FastEthernet0/0

Ip address 192.168.209.254 255.255.255.0
Ip policy route-map TOS-Mark
Load-interval 30

 

This is also a common mpls ce-side configuration, and the qos part can basically be used as a template.
