- Classic EIGRP Problem
- Loses bandwidth visibility at 10 Gbps.
- Anything 10Gbps and above has metric of 256
- Same with Delay, anything above 1 GigE = 10
- Wide Metrics
- Only in named mode.
- Automatically turned on when using named mode.
- 64 bits.
- Scales higher
- Bandwidth
- 10^7 * 65536/Interface Bandwidth
- Called Throughput
- Delay
- Uses picoseconds instead of microseconds.
- Called Latency
- IOS RIB
- Only supports 32 bit metrics
- After DUAL runs, metric is scaled down to fit into RIB.
- Default scale is 1/128, can be modified with below command
- ‘metric rib-scale’
- All the way down into AF AS
- ‘metric rib-scale’
