Re: MX and AE loadbalacing

Hi,

 

On MX, can you try configuring load-balancing per-packet configuration? It says per-packet, but it really is per-flow load-balancing in implementation.

 

[edit routing-options forwarding-table]

export load-balancing-policy;

[edit policy-options]

policy-statement

load-balancing-policy

{   

   then

{        load-balance per-packet;    }}

 

To answer some of the questions you had posed - 

 

 - Load-balancing across AE member links is performed based on a hashing funtion. Hash computation is performed in hardware on ingress PFE's lookup chip with a combination of several functions. The output of this operation is generation of several

 

You can also try per-family load-balancing. For example, if you plan to configure load balancing for IPv4 transit traffic, you may configure lb using keys dervied from L3 and L4 headers.

 

For verification, you may use the following operational mode command - 

 

request pfe execute target fpc<FPC NUMBER FOR INGRESS PORT> command "show jnh lb"

[...]            IIF-V4: Yes          SPORT-V4: Yes          DPORT-V4: Yes               TOS: No       GTP-TEID-V4: No           

                  IIF-V6: Yes          SPORT-V6: Yes          DPORT-V6: Yes     TRAFFIC_CLASS: No       GTP-TEID-V6: No         

                 IIF-MPLS: Yes      MPLS_PAYLOAD: Yes          ETHER_PW: Yes          MPLS_EXP: No        CW_PRESENT: No[...]

 

Some options for family inet load-balancing - 

 

{master}[edit]jnpr@R1-RE0# set forwarding-options enhanced-hash-key family inet ?

Possible completions:

+ apply-groups         Groups from which to inherit configuration data

+ apply-groups-except  Don't inherit configuration data from these groups 

gtp-tunnel-endpoint-identifier  Include TEID in the hash key for GTP-U packets 

incoming-interface-index  Include incoming interface index in the hash key 

no-destination-port  Omit IP destination port in the hash key 

no-source-port       Omit IP source port in the hash key 

type-of-service     Include TOS byte in the hash key
