hi all, i have anissue due to a possibile misconfig with load-balan in an lacp. my platform is asr9001 with ios-xr 5.3.3. this device is connected to a switch with two bundled lacp ports. the be interface + phy are configured this way:
interface Bundle-Ether102.2110
vrf lte-gtp-bearer
ipv4 address 10.247.112.1/24
ipv4 unreachables disable
encapsulation dot1q 2110
interface GigabitEthernet0/0/0/10 - 11
bundle id 102 mode active
lacp period 100
load-interval 30
basically what i have here is the default gw for a lan connected to a switch reachable via be. the problem is in the download part (output of be102 to the switch).
the tipology of traffic present is many sources in the lan to only one destination reachable via default gw. so the return traffic should be hashed from one src ip to many dst ip, and , afaik, being a l2 should be a l2 hashing.
so:
1) i have found the possibility of a l2 balancing only under a l2vpn. which is not my case
2) wrong thing if i try to balance per dst-ip
3) any help very very welcome
below some pasted output:
