The event in Dunloy yesterday marked the 30th anniversary of the deaths of IRA men Declan Martin and Henry Hogan, who were killed in a gun fight in which a soldier also died in February 1984.
The parade involved a number of bands and several hundred participants and spectators.
There had been calls for the Parades Commission to rethink its decision to give the march the go-ahead without any restrictions being placed on it.
Unionists drew parallels with last summer's republican march through Castlederg, and criticised the parade for "glorifying terrorism".
However, Sinn Fein said the Dunloy event was a dignified commemoration of two local republicans in a predominantly nationalist town.
Many loyal order parades have been stopped from marching in Dunloy for more than a decade.
