Out of order, an AS is overridden, we see frames dropping, we
sniff a bit and it turns out, sfps are burning, we are in a
place right now where ping and pong are jittery, their latency
is tested, they cant strengthen their icmp bond with a warm
bfd message, how can they keep everyone in ACK, safe from
teardown and dampening, with this kind of ixp relationship??!
but oh admin, we know forwarding works in its own mysterious
ways. We are left with two non rfc compliant scavengers,
bastard 802.1ah fools in a leaky yet shaped, buffer display of
some runts and nimbles, and a giant too. </span></p>

start their life of a packet, leaving one interface to a
neighbor, from an adjacency to a peer, an endless loop, its a
prefix hijack, but as they move from one stack to another,
finding their way through a tunnel of memory failures and
RMAs, one hell of an LSP ride, through firewall horrors and
MTU mismatches, leaving behind, a sea of syslog messages and
snmp alarms. Anyway, Their ttl expired and one funny access
list abruptly denies them life, sending them to Null0, where
they can be peacefully discarded.</span></p>
