Cisco 7606 - PortChannel - Service Instance - Single VLAN - /30

[gfreitasf]

Hello!

 I wonder if there is some way to balance traffic between a PortChannel with 2 channels of 10G and a single vlan with a prefix / 30 using service instance? 

 I ask this because I'm now a PortChannel between 2 routers using service instance on a single vlan, this vlan is responsible for various transport EoMPLS, I have done experiments using the system load-balance weigthed and it still fails, the channels are configured as passive as below: 

 interface TenGigabitEthernet1/1
 mtu 9216
 no ip address
 ip flow ingress
 history BPS
 mls netflow sampling
 storm-control broadcast level 10.00
 storm-control multicast level 10.00
 channel-group 1 mode passive link 1
end

interface TenGigabitEthernet1/2
 mtu 9216
 no ip address
 history BPS
 mls netflow sampling
 storm-control broadcast level 10.00
 storm-control multicast level 10.00
 channel-group 1 mode passive link 2
end

interface Port-channel1
 mtu 9216
 no ip address
 no ip unreachables
 no ip proxy-arp
 ip flow ingress
 mls netflow sampling
 storm-control broadcast level 10.00
 storm-control multicast level 10.00
 no keepalive

EtherChannel Load-Balancing Configuration:

        src-dst-mixed-ip-port vlan included

        mpls label-ip

EtherChannel Load-Balancing Addresses Used Per-Protocol:

Non-IP: Source XOR Destination MAC address

  IPv4: Source XOR Destination IP address and TCP/UDP (layer-4) port number

  IPv6: Source XOR Destination IP address

  MPLS: Label or IP

The services instances that are different of the 530 are only MPLS transport that travels on vlan 530, but TX traffic goes some only interface in a PortChannel.

 the question is whether there is any way to make traffic stay balanced across the two interfaces since the src / dst ip is the same.
