Description (partial)


Records are collected, but never exported by PREFIX-TOS (BGP-NH-TOS, however, is exporting something).

IOS version: 12.0(33)S2

1. PREFIX-TOS on input;
2. BGP-NH-TOS on input+output on another subinterface;
3. IP CEF load-sharing algorithm universal;
4. Exporter source address is set up automatically, not to the Loopback address, not to the address interfaces, where export is going through;
5. Interfaces, where monitors are applied, are in VRFs;
6. Export is done via global routing table;
7. Two equal cost paths to the collector exists;
8. There is no path to the collector in VRF, that corresponds to the interface, where PREFIX-TOS is applied.
