I am starting out new with RSVP and have read some documents on Cisco's website regarding the RSVP configuration. I have to say I still feel a bit lost with RSVP.
Firstly a description of my network. I have a 6 site WAN. Every site has a VoIP phone. Each Cisco 1841 at every site has hard QoS enabled where a specific amount of b/width had been assigned to the QoS and the remaining bandwidth is used for data. The head office has the internet connection which is used for external calls via the PBX. That said I would now like to configure RSVP but there are a few config questions.
From the Cisco doc it seems I can only have 2 sites to use RSVP? Is that correct? I don't think I believe that, but I would like to confirm this.
looking at the following command:
ip rsvp bandwidth interface-kbps single-flow-kbps ->
1.) If I have a multi site, do I need to configure the single-flow-kbps?
2.) How will this affect traffic flow? (ie will it slow down multiple sites or not)
ip rsvp reservation command has session-dport & sender sport. However the VoIP phones use rtp & sip, so that means I have multiple destination & source ports. Can I go ahead and put this command in several times for each port used by rtp & sip?
A problem I noticed on my RSVP reservation command is that the router changes the sender-address to 0.0.0.0 Why is that? How can I fix that and prevent it from happening?
