The configured interval, in hundredths of a second, between EGP Poll command retransmissions to this neighbor, the RFC 904 t3 timer. This controls how often the local system asks this specific legacy peer for routing updates, so a longer interval means slower propagation of any route changes learned from that peer. Example: egpNeighIntervalPoll set much longer than egpNeighIntervalHello for the same peer means Hello keepalives are frequent but routing-update requests to that peer are comparatively infrequent.
