Hi Mark, If traffic matches a ipv6-glean then it is destined to a host on an attached subnet that does not yet have an ND entry. Matching the glean will generate an ND solicitation to that host, but these are rate limited. An address overflow can happen when:
1. when the rate limiting kicks in. 2. the egress link is down 3. some other reasons but I doubt that’s the case here: see src/vnet/ip-neoghbor/ip6_neighbor.c:202 for details. /neale From: vpp-dev@lists.fd.io <vpp-dev@lists.fd.io> on behalf of mark antony via lists.fd.io <mark.antonnyy.1984=gmail....@lists.fd.io> Date: Wednesday, 22 September 2021 at 18:05 To: vpp-dev@lists.fd.io <vpp-dev@lists.fd.io> Subject: [vpp-dev] getting ip6-glean:address overflow drops Hi all, I get about 5 million packet drops due to ip6-glean: address overflow drops. I attached my "vppctl sh error" command result. I am sure about my configuration. What could be the possible reasons for this error? thanks, mark
