Hello,
seems very simple, but..:
Setup: 2 VMs on different ESX-Servers OpenSuSE 11.3 bird 1.2.5 (IPv4 and IPv6 in parallel)
Symptoms: IPv4 is working perfectly IPv6-BGP-Session does not come up.
FYI, the problem turned out to be a problem in kernel/driver/hardware related to network offloading. It was workarounded by disabling all network offloading on that device (ethtool -k). The problem manifested by the BGP protocol stuck in OpenSent state (the OPEN message was sent with incorrect checksum and discarded by the other side). -- Elen sila lumenn' omentielvo Ondrej 'SanTiago' Zajicek (email: santiago@crfreenet.org) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."
