[pim] What is the value of 'infinity'

[John Zwiebel <jzwiebel at cisco.com>]

It may seem like a silly question, but I've found some interop
problems for bidir DF-elections where some have selected 'infinity'
to be 0x7fffffff and some have selected it to be 0xffffffff.

Given the info below, what is "infinity"?

The PIM RFCs (2117 and 2362) have the following statements -

  3.5.1 Sending Asserts
     ...
     If route is not found, use metric preference of 0x7fffffff
     and metric 0xffffffff.

the new PIM sparse-mode spec says:

  assert_metric
    infinite_assert_metric() {
    return {1,infinity,infinity,0}
  }
