FS#1574 - DS-LITE interface toggles up and down, slowdown access #772

Closed aparcar closed 6 years ago

LinuxfarmerHH:

TP-Link Archer C7 V2 behind Fritz6360 cable as bridge. OpenWrt SNAPSHOT r7066-060e1ecefa / LuCI Master (git-18.151.24607-5452cc2)

Using follwing setup the interface wan is switched on and off every second, visible in system.log what slowdown the link to 1/3 and extends pings above 100ms. Mission critical streams with less buffer on IPv4 do stutter by these breaks. System load on the router is higher than necessary, hope that can be fixex until V18 comes out.

dedeckeh:

Is there any reason why you create a static wan dslite interface and not use the dynamic created wan6_4 interface by the dhcpv6 script in case the AFTR option is received ?

You cannot have both together; if you don't want a dynamic dslite interface being created by the dhcpv6 script you need to set iface_dslite to 0 in the wan6 network config or use the dynamic created dslite interface and remove the wan interface network config.

LinuxfarmerHH:

Had a static wan interface because of the AFTR ip address that need to be placed somewhere.

Yes and with disabled dynamic creation the bug disappears, so this can be closed.

Thanks for that:-)
