Delegations from the SDLP and Sinn Fein have held separate meetings with the Parades Commission.
Police were attacked with petrol bombs and blast bombs
The meetings were held in advance of a loyal order parade through an area which has seen violence on several occasions.
The Apprentice Boys are set to parade past the Ardoyne shops in north Belfast - the scene of violence following an Orange Order parade on 12 July.
About 100 police officers were injured as trouble erupted on the return leg.
The SDLP's Alex Attwood said the party provided information to the commission "regarding the presence of senior UVF members at the head of the Orange Parade at Ardoyne on 12 July".
"The Parades Commission must crack down on this sort of activity. It is unacceptable," Mr Attwood said.
His party colleague Pat Convery said: "The SDLP made it clear that no apprentice parade should pass the front of Ardoyne shops in mid August."
The Sinn Fein delegation included Pat Doherty, Alex Maskey, Kathy Stanton and Tierna Cunningham.
"Sinn Fein is demanding that the Parades Commission prevent this march from travelling along this contentious route," Mr Doherty said.
"People need to bear in mind that forcing sectarian parades through areas where they are unwanted does major damage to the task of conflict resolution."
